Jicofo error: "Can not invite participant, no bridge available .. Failed to select a bridge for Participant"

Hello
I am using Raspberry Pi 4, 8GB with Ubuntu to deploy Jitsi Meet. For 2 users it works fine, but once a third user join it all crashes.
Yesterday it didn’t crash somehow and I tried a meeting of 6 participants (5 mobiles and 1laptop) but it didn’t allow audio/video.
So today I un-installed the whole thing, re-installed it, but the problem isn’t solved.
I used the quick installation guide. Forwarded ports 80,443,4443,5349/tcp and 10000,3478/udp in my firewall. No configurations were made except /etc/jitsi/videobridge/sip-communicator.properties behind NAT.

Vesrions:

Btw during installation I haven’t installed gnupg, nginx-full packages because a video I followed once didn’t
Any help would be truly appreciated.

Check your firewall to make sure all required ports are open and accessible. Check port 10000/UDP in particular - make sure it’s open and properly forwarded, if behind a NAT.

Its forwarded just like the others:


also tried forwarding the range 10000-20000/udp and same problem

  • tried modifying > /etc/jitsi/videobridge/sip-communicator.properties and added this line:

`org.jitsi.videobridge.SINGLE_PORT_HARVESTER_PORT 3478

to change the port from 10000 to 3478 and no change, it just became slower
