Can't send an email, no internet access from app container #1911

Version:

Description of the bug and steps to reproduce: I have installed Listmonk using Docker, I can log into the app on my server can add lists, campaigns, subscribers, etc. but I can't send an email when I setup SMTP parameters (the parameters are correct). I got the error: dial tcp 213.156.68.104:587: connect: network is unreachable I'm on an IPV6 only server with a DNS64.

I tried to ping on the app container by I can't to any domain/IP. So I conclude that the container does not have internet access. Is this normal ? Thank you for any help.

This is not normal. It must be a firewall configuration issue.

Thank you for your response. All my outgoing traffic is open so for SMTP this shouldn't be a problem. What problem could be the cause of the error in the firewall?
