Hey Pawel Zaras ,
The hostname provided (FQDN) is not reachable and hence it can't grab the certificate associated. If you are not using a registered Domain, an entry inside the containers should exist at `/etc/hosts` pointing `NGINX_IP FQDN`. This should automatically be set, unless your IP at the beginning of installation is wrong or your docker containers can't communicate. Can you cat `/etc/hosts` inside the pod and attach.
Is this a local VM or on cloud ?
