Problems with Jitsi and IPv6

Hello.

I installed jitsi meet using the official documentation on a debian 10.3 system without any firewall. In addition I activated authentication.

This worked now for a few weeks and I thought I should add IPv6. The server has native IPv6 and so I just added a AAAA record for the Domain and thought this would be enough. The server processes seem to bind to :: and there is no IPv6 firewall as well.

Now I get both with the app and with chromium the error “conference.videobridgeNotAvailable”.

Do I need to add the IPv6 address to some config or add the ipv4 address for some internal service connecting to another internal service that is not supporting ipv6, yet?
