-If you are logging a bug or feature request, please search the current open issues to see if there is already a bug or feature opened.
+If you have a question or want to request a feature, please **DO NOT SUBMIT** a new issue.
 
-For bugs, the easier you make it to reproduce the issue you see, the easier and faster it can get fixed.  If you can provide a script or docker-compose file that reproduces the problems, that is very helpful.
+Instead please use the relevant Discussions section's category:

+
+## Bugs
+
+If you are logging a bug, please search the current open issues first to see if there is already a bug opened.
+
+For bugs, the easier you make it to reproduce the issue you see and the more initial information you provide, the easier and faster the bug can be identified and can get fixed.
+
+Please at least provide:
+- the exact nginx-proxy version you're using (if using `latest` please make sure it is up to date and provide the version number printed at container startup).
+- complete configuration (compose file, command line, etc) of both your nginx-proxy container(s) and proxied containers. You should redact sensitive info if needed but please provide **full** configurations.
+- generated nginx configuration obtained with `docker exec nameofyournginxproxycontainer nginx -T`
+
+If you can provide a script or docker-compose file that reproduces the problems, that is very helpful.
+
+## General advice about `latest`
+
+Do not use the `latest` tag for production setups.
+
+`latest` is nothing more than a convenient default used by Docker if no specific tag is provided, there isn't any strict convention on what goes into this tag over different projects, and it does not carry any promise of stability.
+
+Using `latest` will most certainly put you at risk of experiencing uncontrolled updates to non backward compatible versions (or versions with breaking changes) and makes it harder for maintainers to track which exact version of the container you are experiencing an issue with.
+
+This recommendation stands for pretty much every Docker image in existence, not just nginx-proxy's ones. 
 
 Thanks,
-Jason

 ### Usage
 
 To run it:
 
-    $ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro nginxproxy/nginx-proxy
+```console
+docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro nginxproxy/nginx-proxy
+```
 
 Then start any containers you want proxied with an env var `VIRTUAL_HOST=subdomain.youdomain.com`
 
-    $ docker run -e VIRTUAL_HOST=foo.bar.com  ...
+```console
+docker run -e VIRTUAL_HOST=foo.bar.com  ...
+```
 
 The containers being proxied must [expose](https://docs.docker.com/engine/reference/run/#expose-incoming-ports) the port to be proxied, either by using the `EXPOSE` directive in their `Dockerfile` or by using the `--expose` flag to `docker run` or `docker create` and be in the same network. By default, if you don't pass the --net flag when your nginx-proxy container is created, it will only be attached to the default bridge network. This means that it will not be able to connect to containers on networks other than bridge.
 
-Provided your DNS is setup to forward foo.bar.com to the host running nginx-proxy, the request will be routed to a container with the VIRTUAL_HOST env var set.
+Provided your DNS is setup to forward foo.bar.com to the host running nginx-proxy, the request will be routed to a container with the `VIRTUAL_HOST` env var set.

+Note: providing a port number in `VIRTUAL_HOST` isn't suported, please see [virtual ports](https://github.com/nginx-proxy/nginx-proxy#virtual-ports) or [custom external HTTP/HTTPS ports](https://github.com/nginx-proxy/nginx-proxy#custom-external-httphttps-ports) depending on what you want to achieve.

 ### Wildcard Hosts
 
-You can also use wildcards at the beginning and the end of host name, like `*.bar.com` or `foo.bar.*`. Or even a regular expression, which can be very useful in conjunction with a wildcard DNS service like [xip.io](http://xip.io), using `~^foo\.bar\..*\.xip\.io` will match `foo.bar.127.0.0.1.xip.io`, `foo.bar.10.0.2.2.xip.io` and all other given IPs. More information about this topic can be found in the nginx documentation about [`server_names`](http://nginx.org/en/docs/http/server_names.html).

Or even a regular expression, which can be very useful in conjunction with a wildcard DNS service like [nip.io](https://nip.io) or [sslip.io](https://sslip.io), using `~^foo\.bar\..*\.nip\.io` will match `foo.bar.127.0.0.1.nip.io`, `foo.bar.10.0.2.2.nip.io` and all other given IPs. More information about this topic can be found in the nginx documentation about [`server_names`](http://nginx.org/en/docs/http/server_names.html).

+### Path-based Routing
+
+You can have multiple containers proxied by the same `VIRTUAL_HOST` by adding a `VIRTUAL_PATH` environment variable containing the absolute path to where the container should be mounted. For example with `VIRTUAL_HOST=foo.example.com` and `VIRTUAL_PATH=/api/v2/service`, then requests to http://foo.example.com/api/v2/service will be routed to the container. If you wish to have a container serve the root while other containers serve other paths, give the root container a `VIRTUAL_PATH` of `/`.  Unmatched paths will be served by the container at `/` or will return the default nginx error page if no container has been assigned `/`.
+It is also possible to specify multiple paths with regex locations like `VIRTUAL_PATH=~^/(app1|alternative1)/`. For further details see the nginx documentation on location blocks. This is not compatible with `VIRTUAL_DEST`.
+
+The full request URI will be forwarded to the serving container in the `X-Original-URI` header.
+
+**NOTE**: Your application needs to be able to generate links starting with `VIRTUAL_PATH`. This can be achieved by it being natively on this path or having an option to prepend this path. The application does not need to expect this path in the request.
+
+#### VIRTUAL_DEST
+
+This environment variable can be used to rewrite the `VIRTUAL_PATH` part of the requested URL to proxied application. The default value is empty (off).
+Make sure that your settings won't result in the slash missing or being doubled. Both these versions can cause troubles.
+
+If the application runs natively on this sub-path or has a setting to do so, `VIRTUAL_DEST` should not be set or empty.
+If the requests are expected to not contain a sub-path and the generated links contain the sub-path, `VIRTUAL_DEST=/` should be used.
+
+```console
+$ docker run -d -e VIRTUAL_HOST=example.tld -e VIRTUAL_PATH=/app1/ -e VIRTUAL_DEST=/ --name app1 app
+```
+
+In this example, the incoming request `http://example.tld/app1/foo` will be proxied as `http://app1/foo` instead of `http://app1/app1/foo`.
+
+#### Per-VIRTUAL_PATH location configuration
+
+The same options as from [Per-VIRTUAL_HOST location configuration](#Per-VIRTUAL_HOST-location-configuration) are available on a `VIRTUAL_PATH` basis.
+The only difference is that the filename gets an additional block `HASH=$(echo -n $VIRTUAL_PATH | sha1sum | awk '{ print $1 }')`. This is the sha1-hash of the `VIRTUAL_PATH` (no newline). This is done filename sanitization purposes.
+The used filename is `${VIRTUAL_HOST}_${HASH}_location`
+
+The filename of the previous example would be `example.tld_8610f6c344b4096614eab6e09d58885349f42faf_location`.
+
+#### DEFAULT_ROOT
+
+This environment variable of the nginx proxy container can be used to customize the return error page if no matching path is found. Furthermore it is possible to use anything which is compatible with the `return` statement of nginx.
+
+Exception:  If this is set to the string `none`, no default `location /` directive will be generated.  This makes it possible for you to provide your own `location /` directive in your [`/etc/nginx/vhost.d/VIRTUAL_HOST`](#per-virtual_host) or [`/etc/nginx/vhost.d/default`](#per-virtual_host-default-configuration) files.
+
+If unspecified, `DEFAULT_ROOT` defaults to `404`.
+
+Examples (YAML syntax):
+
+  * `DEFAULT_ROOT: "none"` prevents `nginx-proxy` from generating a default `location /` directive.
+  * `DEFAULT_ROOT: "418"` returns a 418 error page instead of the normal 404 one.
+  * `DEFAULT_ROOT: "301 https://github.com/nginx-proxy/nginx-proxy/blob/main/README.md"` redirects the client to this documentation.
+
+Nginx variables such as `$scheme`, `$host`, and `$request_uri` can be used.  However, care must be taken to make sure the `$` signs are escaped properly.  For example, if you want to use `301 $scheme://$host/myapp1$request_uri` you should use:
+
+* Bash: `DEFAULT_ROOT='301 $scheme://$host/myapp1$request_uri'`
+* Docker Compose yaml: `- DEFAULT_ROOT: 301 $$scheme://$$host/myapp1$$request_uri`
+
 
 ### Multiple Networks
 
@@ -108,18 +175,26 @@ With the addition of [overlay networking](https://docs.docker.com/engine/usergui
 If you want your `nginx-proxy` container to be attached to a different network, you must pass the `--net=my-network` option in your `docker create` or `docker run` command. At the time of this writing, only a single network can be specified at container creation time. To attach to other networks, you can use the `docker network connect` command after your container is created:
 
 ```console
-$ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro \
+docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro \
     --name my-nginx-proxy --net my-network nginxproxy/nginx-proxy
-$ docker network connect my-other-network my-nginx-proxy
+docker network connect my-other-network my-nginx-proxy
 ```
 
 In this example, the `my-nginx-proxy` container will be connected to `my-network` and `my-other-network` and will be able to proxy to other containers attached to those networks.
 
+### Custom external HTTP/HTTPS ports
+
+If you want to use `nginx-proxy` with different external ports that the default ones of `80` for `HTTP` traffic and `443` for `HTTPS` traffic, you'll have to use the environment variable(s) `HTTP_PORT` and/or `HTTPS_PORT` in addition to the changes to the Docker port mapping. If you change the `HTTPS` port, the redirect for `HTTPS` traffic will also be configured to redirect to the custom port. Typical usage, here with the custom ports `1080` and `10443`:
+
+```console
+docker run -d -p 1080:1080 -p 10443:10443 -e HTTP_PORT=1080 -e HTTPS_PORT=10443 -v /var/run/docker.sock:/tmp/docker.sock:ro nginxproxy/nginx-proxy
+```
+
 ### Internet vs. Local Network Access
 
 If you allow traffic from the public internet to access your `nginx-proxy` container, you may want to restrict some containers to the internal network only, so they cannot be accessed from the public internet.  On containers that should be restricted to the internal network, you should set the environment variable `NETWORK_ACCESS=internal`.  By default, the *internal* network is defined as `127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16`.  To change the list of networks considered internal, mount a file on the `nginx-proxy` at `/etc/nginx/network_internal.conf` with these contents, edited to suit your needs:
 
-```

+### Custom log format
+
+If you want to use a custom log format, you can set `LOG_FORMAT=xxx` on the proxy container. 
+
+With docker compose take care to escape the `$` character with `$$` to avoid variable interpolation. Example: `$remote_addr` becomes `$$remote_addr`.
 
 ### Default Host
 
 To set the default host for nginx use the env var `DEFAULT_HOST=foo.bar.com` for example
 
-    $ docker run -d -p 80:80 -e DEFAULT_HOST=foo.bar.com -v /var/run/docker.sock:/tmp/docker.sock:ro nginxproxy/nginx-proxy
+```console
+docker run -d -p 80:80 -e DEFAULT_HOST=foo.bar.com -v /var/run/docker.sock:/tmp/docker.sock:ro nginxproxy/nginx-proxy
+```
 
 nginx-proxy will then redirect all requests to a container where `VIRTUAL_HOST` is set to `DEFAULT_HOST`, if they don't match any (other) `VIRTUAL_HOST`. Using the example above requests without matching `VIRTUAL_HOST` will be redirected to a plain nginx instance after running the following command:

-The contents of `/path/to/certs` should contain the certificates and private keys for any virtual

 #### Diffie-Hellman Groups
 
-Diffie-Hellman groups are enabled by default, with a pregenerated key in `/etc/nginx/dhparam/dhparam.pem`.
-You can mount a different `dhparam.pem` file at that location to override the default cert.
-To use custom `dhparam.pem` files per-virtual-host, the files should be named after the virtual host with a
-`dhparam` suffix and `.pem` extension. For example, a container with `VIRTUAL_HOST=foo.bar.com`
-should have a `foo.bar.com.dhparam.pem` file in the `/etc/nginx/certs` directory.
+[RFC7919 groups](https://datatracker.ietf.org/doc/html/rfc7919#appendix-A) with key lengths of 2048, 3072, and 4096 bits are [provided by `nginx-proxy`](https://github.com/nginx-proxy/nginx-proxy/dhparam). The ENV `DHPARAM_BITS` can be set to `2048` or `3072` to change from the default 4096-bit key. The DH key file will be located in the container at `/etc/nginx/dhparam/dhparam.pem`. Mounting a different `dhparam.pem` file at that location will override the RFC7919 key.
 
-> NOTE: If you don't mount a `dhparam.pem` file at `/etc/nginx/dhparam/dhparam.pem`, one will be generated
-at startup.  Since it can take minutes to generate a new `dhparam.pem`, it is done at low priority in the
-background.  Once generation is complete, the `dhparam.pem` is saved on a persistent volume and nginx
-is reloaded.  This generation process only occurs the first time you start `nginx-proxy`.
+To use custom `dhparam.pem` files per-virtual-host, the files should be named after the virtual host with a `dhparam` suffix and `.pem` extension. For example, a container with `VIRTUAL_HOST=foo.bar.com` should have a `foo.bar.com.dhparam.pem` file in the `/etc/nginx/certs` directory.

 #### Wildcard Certificates

 #### SNI
 
-If your certificate(s) supports multiple domain names, you can start a container with `CERT_NAME=<name>`
-to identify the certificate to be used.  For example, a certificate for `*.foo.com` and `*.bar.com`
-could be named `shared.crt` and `shared.key`.  A container running with `VIRTUAL_HOST=foo.bar.com`
-and `CERT_NAME=shared` will then use this shared cert.

 #### OCSP Stapling
-To enable OCSP Stapling for a domain, `nginx-proxy` looks for a PEM certificate containing the trusted
-CA certificate chain at `/etc/nginx/certs/<domain>.chain.pem`, where `<domain>` is the domain name in
-the `VIRTUAL_HOST` directive.  The format of this file is a concatenation of the public PEM CA
-certificates starting with the intermediate CA most near the SSL certificate, down to the root CA.  This is
-often referred to as the "SSL Certificate Chain".  If found, this filename is passed to the NGINX
-[`ssl_trusted_certificate` directive](http://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_trusted_certificate)
-and OCSP Stapling is enabled.

-should provide compatibility with clients back to Firefox 27, Android 4.4.2, Chrome 31, Edge, IE 11 on Windows 7,
-Java 8u31, OpenSSL 1.0.1, Opera 20, and Safari 9.  Note that the DES-based TLS ciphers were removed for security.
-The configuration also enables HSTS, PFS, OCSP stapling and SSL session caches.  Currently TLS 1.2 and 1.3
-are supported.

 The default behavior for the proxy when port 80 and 443 are exposed is as follows:
 
-* If a container has a usable cert, port 80 will redirect to 443 for that container so that HTTPS
-is always preferred when available.
-* If the container does not have a usable cert, a 503 will be returned.
+* If a virtual host has a usable cert, port 80 will redirect to 443 for that virtual host so that HTTPS is always preferred when available.
+* If the virtual host does not have a usable cert, but `default.crt` and `default.key` exist, those will be used as the virtual host's certificate and the client browser will receive a 500 error.
+* If the virtual host does not have a usable cert, and `default.crt` and `default.key` do not exist, TLS negotiation will fail (see [Missing Certificate](#missing-certificate) below).
 
-Note that in the latter case, a browser may get an connection error as no certificate is available
-to establish a connection.  A self-signed or generic cert named `default.crt` and `default.key`
-will allow a client browser to make a SSL connection (likely w/ a warning) and subsequently receive
-a 500.
+To serve traffic in both SSL and non-SSL modes without redirecting to SSL, you can include the environment variable `HTTPS_METHOD=noredirect` (the default is `HTTPS_METHOD=redirect`). You can also disable the non-SSL site entirely with `HTTPS_METHOD=nohttp`, or disable the HTTPS site with `HTTPS_METHOD=nohttps`. `HTTPS_METHOD` can be specified on each container for which you want to override the default behavior or on the proxy container to set it globally. If `HTTPS_METHOD=noredirect` is used, Strict Transport Security (HSTS) is disabled to prevent HTTPS users from being redirected by the client. If you cannot get to the HTTP site after changing this setting, your browser has probably cached the HSTS policy and is automatically redirecting you back to HTTPS. You will need to clear your browser's HSTS cache or use an incognito window / different browser.

+#### Missing Certificate
+
+If HTTPS is enabled for a virtual host but its certificate is missing, nginx-proxy will configure nginx to use the default certificate (`default.crt` with `default.key`) and return a 500 error.
+
+If the default certificate is also missing, nginx-proxy will configure nginx to accept HTTPS connections but fail the TLS negotiation.  Client browsers will render a TLS error page.  As of March 2023, web browsers display the following error messages:

+### Upstream (Backend) Server HTTP Load Balancing Support
+
+> **Warning**
+> This feature is experimental.  The behavior may change (or the feature may be removed entirely) without warning in a future release, even if the release is not a new major version.  If you use this feature, or if you would like to use this feature but you require changes to it first, please [provide feedback in #2195](https://github.com/nginx-proxy/nginx-proxy/discussions/2195).  Once we have collected enough feedback we will promote this feature to officially supported.
+
+If you have multiple containers with the same `VIRTUAL_HOST` and `VIRTUAL_PATH` settings, nginx will spread the load across all of them.  To change the load balancing algorithm from nginx's default (round-robin), set the `com.github.nginx-proxy.nginx-proxy.loadbalance` label on one or more of your application containers to the desired load balancing directive.  See the [`ngx_http_upstream_module` documentation](https://nginx.org/en/docs/http/ngx_http_upstream_module.html) for available directives.
+
+> **Note**
+> * Don't forget the terminating semicolon (`;`).
+> * If you are using Docker Compose, remember to escape any dollar sign (`$`) characters (`$` becomes `$$`).
+
+Docker Compose example:
+
+```yaml
+services:
+  nginx-proxy:
+    image: nginxproxy/nginx-proxy
+    ports:
+      - "80:80"

+> **Warning**

If you use this feature, or if you would like to use this feature but you require changes to it first, please [provide feedback in #2194](https://github.com/nginx-proxy/nginx-proxy/discussions/2194).  Once we have collected enough feedback we will promote this feature to officially supported.
+
+To enable HTTP keep-alive between `nginx-proxy` and a backend server, set the `com.github.nginx-proxy.nginx-proxy.keepalive` label on the server's container to the desired maximum number of idle connections. See the [nginx keepalive documentation](https://nginx.org/en/docs/http/ngx_http_upstream_module.html#keepalive) and the [Docker label documentation](https://docs.docker.com/config/labels-custom-metadata/) for details.
+
+### Headers
+
+By default, `nginx-proxy` forwards all incoming request headers from the client to the backend server unmodified, with the following exceptions:
+
+  * `Connection`: Set to `upgrade` if the client sets the `Upgrade` header, otherwise set to `close`. (Keep-alive between `nginx-proxy` and the backend server is not supported.)
+  * `Proxy`: Always removed if present. This prevents attackers from using the so-called [httpoxy attack](http://httpoxy.org). There is no legitimate reason for a client to send this header, and there are many vulnerable languages / platforms (`CVE-2016-5385`, `CVE-2016-5386`, `CVE-2016-5387`, `CVE-2016-5388`, `CVE-2016-1000109`, `CVE-2016-1000110`, `CERT-VU#797896`).
+  * `X-Real-IP`: Set to the client's IP address.
+  * `X-Forwarded-For`: The client's IP address is appended to the value provided by the client. (If the client did not provide this header, it is set to the client's IP address.)
+  * `X-Forwarded-Host`: If the client did not provide this header or if the `TRUST_DOWNSTREAM_PROXY` environment variable is set to `false` (see below), this is set to the value of the `Host` header provided by the client. Otherwise, the header is forwarded to the backend server unmodified.
+  * `X-Forwarded-Proto`: If the client did not provide this header or if the `TRUST_DOWNSTREAM_PROXY` environment variable is set to `false` (see below), this is set to `http` for plain HTTP connections and `https` for TLS connections. Otherwise, the header is forwarded to the backend server unmodified.
+  * `X-Forwarded-Ssl`: Set to `on` if the `X-Forwarded-Proto` header sent to the backend server is `https`, otherwise set to `off`.
+  * `X-Forwarded-Port`: If the client did not provide this header or if the `TRUST_DOWNSTREAM_PROXY` environment variable is set to `false` (see below), this is set to the port of the server that accepted the client's request. Otherwise, the header is forwarded to the backend server unmodified.
+  * `X-Original-URI`: Set to the original request URI.
+
+#### Trusting Downstream Proxy Headers
+
+For legacy compatibility reasons, `nginx-proxy` forwards any client-supplied `X-Forwarded-Proto` (which affects the value of `X-Forwarded-Ssl`), `X-Forwarded-Host`, and `X-Forwarded-Port` headers unchecked and unmodified. To prevent malicious clients from spoofing the protocol, hostname, or port that is perceived by your backend server, you are encouraged to set the `TRUST_DOWNSTREAM_PROXY` value to `false` if:
+
+  * you do not operate a second reverse proxy downstream of `nginx-proxy`, or
+  * you do operate a second reverse proxy downstream of `nginx-proxy` but that proxy forwards those headers unchecked from untrusted clients.
+
+The default for `TRUST_DOWNSTREAM_PROXY` may change to `false` in a future version of `nginx-proxy`. If you require it to be enabled, you are encouraged to explicitly set it to `true` to avoid compatibility problems when upgrading.
+
 ### Custom Nginx Configuration

This file will be used on any virtual host which does not have a `/etc/nginx/vhost.d/{VIRTUAL_HOST}_location` file associated with it.
+
+#### Overriding `location` blocks
+
+The `${VIRTUAL_HOST}_${PATH_HASH}_location`, `${VIRTUAL_HOST}_location`, and `default_location` files documented above make it possible to *augment* the generated [`location` block(s)](https://nginx.org/en/docs/http/ngx_http_core_module.html#location) in a virtual host.  In some circumstances, you may need to *completely override* the `location` block for a particular combination of virtual host and path.  To do this, create a file whose name follows this pattern:
+
+```
+/etc/nginx/vhost.d/${VIRTUAL_HOST}_${PATH_HASH}_location_override
+```
+
+where `${VIRTUAL_HOST}` is the name of the virtual host (the `VIRTUAL_HOST` environment variable) and `${PATH_HASH}` is the SHA-1 hash of the path, as [described above](#per-virtual_path-location-configuration).
+
+For convenience, the `_${PATH_HASH}` part can be omitted if the path is `/`:
+
+```
+/etc/nginx/vhost.d/${VIRTUAL_HOST}_location_override
+```
+
+When an override file exists, the `location` block that is normally created by `nginx-proxy` is not generated.  Instead, the override file is included via the [nginx `include` directive](https://nginx.org/en/docs/ngx_core_module.html#include).
+
+You are responsible for providing a suitable `location` block in your override file as required for your service.  By default, `nginx-proxy` uses the `VIRTUAL_HOST` name as the upstream name for your application's Docker container; see [here](#unhashed-vs-sha1-upstream-names) for details.  As an example, if your container has a `VIRTUAL_HOST` value of `app.example.com`, then to override the location block for `/` you would create a file named `/etc/nginx/vhost.d/app.example.com_location_override` that contains something like this:
+
+```
+location / {
+    proxy_pass http://app.example.com;
+}
+```
 
 #### Per-VIRTUAL_HOST `server_tokens` configuration
 Per virtual-host `servers_tokens` directive can be configured by passing appropriate value to the `SERVER_TOKENS` environment variable. Please see the [nginx http_core module configuration](https://nginx.org/en/docs/http/ngx_http_core_module.html#server_tokens) for more details.
 
+### Unhashed vs SHA1 upstream names
+
+By default the nginx configuration `upstream` blocks will use this block's corresponding hostname as a predictable name. However, this can cause issues in some setups (see [this issue](https://github.com/nginx-proxy/nginx-proxy/issues/1162)). In those cases you might want to switch to SHA1 names for the `upstream` blocks by setting the `SHA1_UPSTREAM_NAME` environment variable to `true` on the nginx-proxy container.
+
+Please note that using regular expressions in `VIRTUAL_HOST` will always result in a corresponding `upstream` block with an SHA1 name.
+
 ### Troubleshooting
 
-In case you can't access your VIRTUAL_HOST, set `DEBUG=true` in the client container's environment and have a look at the generated nginx configuration file `/etc/nginx/conf.d/default`:
+If you can't access your `VIRTUAL_HOST`, inspect the generated nginx configuration:
