engine-1 error when running example

[HollowYUK]

Thank you for this excellent project!

I am encountering an issue when running the"ECHO" in "Example"
When I run the example, engine-1 reports the following errors in the logs:

engine-1 | error: failed to fetch server settings: http status: 404
engine-1 | 2025-10-22 11:00:35,045 - ERROR livekit - livekit_ffi::server::room:149:livekit_ffi::server::room - audio filter cannot be enabled: LiveKit Cloud is required {"pid": 925, "job_id": "AJ_4avcH77wmyHs"}

Could you please advise on how to resolve or troubleshoot this error? Thank you.

Hey, that error is harmless. Our cloud version using a premium feature of LiveKit (Krisp noise cancellation) that is not available locally.

Thank you for your reply. I keep getting the following error when running example: "Failed to start run", maybe this issue is caused by timeout or webrtc server error.
I am deploying gabber-dev using docker-compose and have modified the variable GABBER_PUBLIC_HOST to real ip and changed localhost to 0.0.0.0 in yml file to deploy it on my linux server. Are there any other files or code I need to modify to run it on my server?

Can you try again with the latest main. This PR: #251 may have fixed something in this area. I do see that the livekit room is successfully starting
