Video Quality Impaired - The bridge Channel has been disconnect about jitsi-meet

server-id=jvb3 this part should be different in your different videobridges. Share your nginx config about colibri-ws endpoints and the endpoints used there. You should have
At least 2 rules, one of them should be

location ~ ^/colibri-ws/jvb3/(.*) {
   proxy_pass http://jvb3/colibri-ws/default-id/$1$is_args$args;
...

That should connect to the upstream:

upstream jvb3 {
    zone upstreams 64K;
    server 127.0.0.1:9090;
    keepalive 2;
}

Where the IP address instead of localhost will be the jvb internal address and port 9090 will be accessible from nginx machine to the jvb machine.

Thanks for answer!

There is one virtual machine with jitsi-meet, nginx and two hardware boxes. The videobridge on the VM is jvb1 and is always deactivated. jicofo and nginx are running on this VM.

On the two hardware boxes, only videobridges are running, that's jvb2 and jvb3.

Attached is the nginx conf. There is only one location for colibri-ws with parameter for the videobridges.
nginx.txt

Your nginx config expects that you have a single jvb that is running on the same machine as nginx (on 127.0.0.1:9090) and that its server-id is default-id, it doesn't know anything about a jvb with server-id=jvb3 and the ip address where to reach it.

    # colibri (JVB) websockets for jvb1
    location ~ ^/colibri-ws/default-id/(.*) {
        proxy_pass http://127.0.0.1:9090/colibri-ws/default-id/$1$is_args$args;

You need to fix your nginx config to connect to the two jvbs with correct id that is configured in the jvb.conf and the correct ip address, make sure nginx machine has access on that ip address and port.

Please, when you have questions or problems use the community forum before opening new issues, thank you.

That's strange! I have restored the backup and now everything is working again. With the nginx configuration, which can't work at all :-) All 3 video bridges are active, no problems.
