I had a working instance of jitsi set up on my home server. I tested it out with a three-way meeting between my phone (jitsi app - no wifi so it went out over the cell network), my workstation and another person not on my home network. That went fine apart from feedback between my workstation and my phone when I didn’t have the phone’s mic muted.
All I’ve done to the server is some updates (Debian/Buster - stable) over the last couple of weeks but now I can’t even get the phone to work properly. Worse, a scheduled family get together flopped when all we could do was use the chat function. No one could see or hear anyone else. We just could see our own screens and the initials of the other participants.
I tried retesting it with my phone + workstation and I get exactly the same problem. I can connect to the meeting but can’t see my other device’s video feed nor hear its audio.
The other people used a variety of iPhone, Android, Mac, Windows and Linux systems so this is probably not an issue with their devices. I’ve checked the router port forwarding settings and they haven’t changed. I’ve rebooted the server but that didn’t help.
As a newbie to running a jitsi server, I don’t really know how to fix this. The suggestions I’ve seen for similar problems don’t seem to be related as they were client-side. Any ideas?
