This came up when i wanted to send a mail, so I started looking into the settings and logs.
Connection error: failed to lookup address information: Temporary failure in name resolution
… =\> 400 Bad Request
Vaultwarden Version: 1.29.0
For the logest time my installation worked without a flaw, with me beeing able to send Mails for invitations and stuff. Now my Mails dont Work anymore. The Error seems to be that the container has no Internet Access. I am using Docker. The Network is set up like every other Network as well as a bridge adapter and they all work. Is there any known problem with the Container Image or did the env variables change or do i need new one?

Nothing has changed on the Vaultwarden side regarding anything like that.
So, it probably is something on the Docker side. But it looks like a DNS issue.
Try to see if there is something wrong with the DNS.
