I cannot start more than 2 participants

Hello All,

I installed the dedicated server from the procedure on Ubuntu 16.04.6 LTS and 18.04, but I cannot attend a conference of more than 2 users, if there are 2 on the desktop/laptop it is OK as the 3rd one on the mobile is closing the cameras turn black and there is no audio signal.

a nice week,

Hi and welcome!
A common problem is not doing all the steps from the advance section of quick install guide and browsers media cannot reach jvb and there is no audio or video.
Check your firewall settings, port forwarding and public/private address setting for jvb.

Hello Damian,

After I modified / added the file “/etc/jitsi/videobridge/sip-communicator.properties” IP address. Worked!


I restarted the application and I managed to connect video / audio 2 phones and 2 laptops.

root@instance-2:/etc/jitsi/videobridge# service jitsi-videobridge restart

I checked the ports as they are open and they are OK. 4443 is not open because it is a dedicated server does not use NAT for routing.

Thanks for the reply,
A nice week!
