As was already asked a few times. It seems that jitsi-videobridge and jitsi-videobridge2 are both wrongly listening on UDP6 and are thus not reachable. E.g for SIP integration.
I do not quite understand yet where this behavior is configured. E.g there is a comment about disabling ip6 here https://github.com/jitsi/ice4j/blob/38e7b9226d6e1e790fe3b4ccacfeca64e9c2ed71/doc/configuration.md, but is this related ? If it is WHICH config file exactly (full-path) is to be udpated ?
A lot of the comments here mention keys, but it isn’t always clear where to set those.
I also tried disabling ip6 on ubuntu (18) to no avail.
Any help would be greatly appreciated. It should be mentioned that this also happens in a pure quick install on a fresh ubuntu 18 image. Everything seems to work, but not using UDP port 10000 (using udp6 instead)
