Neither video nor audio on IPv6-only system #7349

Closed memcopy closed 4 years ago

memcopy commented 4 years ago

Description:

I disabled IPv4 on my PC and only kept the IPv6 addresses. After that I visited meet.jit.si. While the website itself works fine, there is neither video nor audio in the conferences. On my own hosted jitsi instance I have the same issues.

I assume IPv6 support is broken, or the default configuration is wrong.

Steps to reproduce:

  1. Remove all ipv4 addresses: ip addr del xxx.xxx.xxx./xx dev ensXXX
  2. Open meet.jit.si in browser
  3. Join conference
  4. Open the same conference in other browser tab
  5. Video and audio are broken

Expected behavior:

I expect the conference to just work because not NAT is involved. This setup should be much simpler without ICE, stun and there-like.

Actual behavior:

No video and audio in the conferences.

Server information:

meet.jit.si

Client information:

This issue is still an issue. WIth an IPv6-only network, without any IPv4 connectivity or NAT64, no calls can be performed. Even with two IPv6-only clients, the call still does not connect.

The web interface is fully functional and does not indicate connectivity issues, but there is no audio/video.

Notable errors from the console:

All of these hostnames - but mainly meet-jit-si-eu-central-1b-s37-jvb-40-78-107.jitsi.net and rtcstats-server.jitsi.net do not resolve to an IPv6 address.

(OT: The only client which seems not to have issues with IPv6 WebRTC is Chromium / Chrome.)
