Starting this container can fail at certbot initialization with this error (reported at the end of /var/log/letsencrypt/letsencrypt.log): HTTPSConnectionPool(host='acme-v02.api.letsencrypt.org', port=443): Max retries exceeded with url: /directory "[Errno -3] Try again" which does not tell much about the real problem and it just sounds like a possible DNS resolution issue. However, by logging into the container after the error above, a simple: wget https://acme-v02.api.letsencrypt.org/directory usually works. It works also the exact same certbot command logged in /var/log/letsencrypt/letsencrypt.log. This has been verified happening for example while installing the contained on a QNAP NAS with a bridged network setup. Turns out that on some systems a small delay is required before running network access operations (e.g. running certbot). Add a tight look to ckeck for a valid resolution of ACMESERVER. Report a clearer error in case we cannot resolve the server withing 1 min. Otherwise, continue with the init script, as soon as nslook is happy. No overheads for generic systems: just a local nslookup will be performed, which response caching will benifit anyway the following certbot connection.
