I’m trying to set up a jitsi-meet instance on Ubuntu 20.04. The setup so far has been successful, I have Let’sEncrypt certificates working, and when using it normally everything seems to work so far.
The problem comes in when one participant connects from a network that sits behind a corporate proxy. The scenario is as follows:
Participant uses latest Firefox, the browser has the proxy settings configured. Opening / joining a conference works but the participant gets no video/audio from other participants. Instead they only see their own video. From the other side you see the placeholder Avatar but no video/audio from that participant. All other participants in the meeting can see and hear each other.
The weird part is: It doesn’t work on meet.jit.si either. It’s the exact same thing.
Some more info and details:
- All users are using Windows 10 and the latest Firefox
- Peer-to-peer is disabled entirely
- The corporate proxy is a squid3 proxy
- The firewall on the jitsi meet instance has the following ports open: TCP 80, 443, 4443 / UDP 10000:20000
If anyone has any pointers for me I would be extremly thankful.
