No connection with Videobridge after update

Hello everyone,

I recently reinstalled Jitsi on my server including all its components due to the update and me wanting to switch from Apache2 to nginx.
I have made a handful of changes, like the stun server, disabling third party integration etc. Also I changed the installation to a secure domain since it will be mainly used by schools and imported my users, I also enabled the new Lobby feature, so far so good. Yesterday i decided to configure a Grafana dashboard for my installtion to monitor the usage, that works aswell. So I am not sure where my problem stems for but it looks like this:
I create a new room, log in and wait for a second participant or more. If one enables his camera, a gray screen appears and after a while his “logo” reapperars. (P2P is disabled)

Since everything else seems to work, I assume its just a problem with JVB. For a short time enabling P2P seemed to have worked, even with more than 2 people in a conference, which i didn’t quite understand.
These are the JVB logs

My Jitsi and Videobride Versions are:
jitsi-meet 2.0.5390-3
jitsi-videobridge2 2.1-416-g2f43d1b4-1
Ubuntu 20.04

The Ports 80/TCP 443/TCP 4443/TCP 10000/UDP are opened on the firewall.

I am more than happy to provide additional Information / config files if needed.
Thank you for your Response

Kind Regards
Niclas

What are the js console logs, are there any errors?

Nothing besides this

I’ve just found out it seems to be a problem with my work network / firewall, since it works from home and over mobile data…
This is still very odd to me because it definitely has worked in the past from the same (unchanged) network, just on an older version of Jitsi running on Apache2.
Is there another reasonable explanation as to how this can occur other than port 10000/UDP being blocked in the local Firewall?

RTT of 3 secs is suspicious. This is network problem.

That confirms it then, thank you very much for your help :slight_smile:
