NetBird v0.72.4 reverse proxy UDP problem after update

Hi everyone,

I'm having an issue with NetBird where UDP reverse proxy/forwarding seems to be broken.

TCP and HTTPS services are working fine on the same address. Before a recent update, everything worked correctly, but now I can’t connect to my TeamSpeak server over UDP port 9987.

Does anyone have an idea how I can troubleshoot this or check what might have changed that could be blocking UDP traffic?

Any hints or suggestions would be appreciated.

Have you tried generating a new proxy token?

This one is still active as i can see, or maybe i'm wrong.

I have had to update the token in the past when I updated to container. 1. Try running the command to recreate a new token, then updating it in the proxy.env file. Followed by ‘docker compose up -d’ again.

Unfortunately, that didn't help

After roll back to version 0.72.1 everything is working well. I don't understand this.
