What do you mean by

I'm getting this error very often when refreshing the app

? It works the first time but errors out after a refresh? How are you running your server? and which version

@dry-elephant-14928 It works the first time but errors out after a refresh - this is the most common scenario. But then after some time it ‘resets’. It works once and after refresh stops working again. The server is spun up with docker compose. The image in use is livekit/livekit-server:v1.2.5

did you use our generator script to create the install? or did you make it custom?

@dry-elephant-14928 I am not aware of any generator script. I think it is custom. There is also similar issue reported on github https://github.com/livekit/livekit/issues/1060

config generator is here: https://docs.livekit.io/oss/deployment/vm/ I would give that a try first and ensure the ports/etc are mapped correctly.

Well, after a week of investigation we restarted my colleague’s router and it started to work fine 🤯 Thank you @dry-elephant-14928 and @adorable-accountant-89790 for helping me with this one 🙏

glad to hear it! I wonder if the router is blocking UDP packets? it's unclear why connection test would work but not example.

@dry-elephant-14928 There was no blocking on the router. But it could cache UDP packets.
