Can make only one to one call

Hi,
I’ve just installed the jitsi sever. It worked fine but when I have one 2 one meeting
When 3rd member join the call video and audio stops for everyone

Did you open your firewall for all of the required ports?

HTTPS

sudo ufw insert 2 allow 443/tcp

turn, 4445 for TLS, 4446 for plain

sudo ufw insert 2 allow 4445/tcp
sudo ufw insert 2 allow 4445/udp
sudo ufw insert 2 allow 4446/tcp
sudo ufw insert 2 allow 4446/udp

incoming network

sudo ufw insert 2 allow in 10000:20000/udp

Thanks for your reply
I tried your recommendation but it didn’t work
The situation is
When meeting has only 2 participants everything (video & audio) works fine. When 3rd participant joins the meeting video and audio stops

With 2 people, connections go directly. They do not relay through the jitsi server.

With 3+ people, they relay through the jitsi server.

So if audio and video stop when 3 people join, it means there is a problem with the relay configuration.

This is not correct.. Only port 10000 is needed.

Fixed my startup script. Thank you!

Thanks
You are right
I fixed the configuration and now working fine
