I am hosting Jitsi along with supporting technologies on the same server.
For some reason users can see themselves but not other users. Sometimes briefly they can see another user then it goes away. Error in balloon says Video quality impaired bridge channel disconnected. I have attached a video that shows my ports opened, bandwidth speed test and console errors to assist with diagnosis.

When the bridge channel (i.e. Colibri websocket) fails to connect you will usually see some error in the browser console which may shed some light on the issue. Most likely either a mistake in nginx config or JVB config, the logs of those services may also contain clues.
Thank you for your thoughts. I took your advice. I cleared the contents of and then inspected the log /var/log/jitsi/jvb.log as the failure occurred.
This one stood out: “java.lang.Exception: Failed to bind single-port”
I searched online and that term immediately brought this post from the community.jitsi.org forum:
The short answer - WEBMIN was running on port 10000 and that was conflicting with the Jitsi meet setup. Though I could have changed the webmin port, I didn’t need it so just uninstalled it. Rebooted for insurance and the problem was resolved.
I am also experiencing this issue. I recently upgraded our jitsi server to the latest everything, including from Ubuntu 18.04 to 20.04. I see the same warning message as soon as 2 people join the meeting. The video quality is superb, and I don’t see any other issues except the warning message on the screen. I don’t have webmin on this server. “lsof |grep :10000” shows jvb is listening on that port. Does anyone have any other suggestions on what else to check?
