What happened?

Hello,

we have configured and deployed jitsi on a kubernetes cluster hosted on digitalocean. The whole setup is exposed behind a nginx proxy server that is configured to proxy UDP connections to the JVB pod.

We have tested the UDP network setup and all the UDP connections are being proxied correctly.

The running configuration include:

ENABLE_XMPP_WEBSOCKET: 'false' PUBLIC_URL: <publi url> JVB_ADVERTISE_IPS: <public ip> DOCKER_HOST_ADDRESS: <public ip>

Untill we have two partecipants there is no problem, if the third partecipant logs in we start seeing on the logs:

With:

• 10.244.0.169 being the nginx ingress internal IP
• 10.244.1.81 being the jvb pod ip address.

Any suggestion ?

Thank you very much!
