Thanks for reaching out, Aditya. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

error: failed to fetch server settings: http status: 404 073407.424 ERROR livekit livekit_ffi:server… - audio filter cannot be enabled: LiveKit Cloud is required Why I am getting this error?

You're seeing two related issues. Short answer: the agent can't reach valid server settings (404) and it's trying to enable a Cloud-only audio filter. Why each error appears • "failed to fetch server settings: http status: 404" The agent requested configuration from your LiveKit server but got a 404 Not Found. That means the URL or endpoint it called is incorrect or the server routing/endpoint isn’t present (room or API path not found). • "audio filter cannot be enabled: LiveKit Cloud is required" Your code is attempting to enable an enhanced audio filter (e.g., BVC/noise cancellation) that is only available on LiveKit Cloud. That feature is unavailable on self-hosted servers and the SDK reports this error. What to do next • Verify

LIVEKIT_URL

is correct and reachable (use the proper wss/http scheme for your deployment). • Confirm the room or API endpoint exists and the server is up. • If self-hosted, remove or disable Cloud-only audio filters (disable BVC/noise_cancellation). Use basic WebRTC suppression or

AudioCaptureOptions

instead. • If you require BVC, run the agent against LiveKit Cloud. If you want, paste the agent startup snippet and the

LIVEKIT_URL

format (redact secrets) and I’ll point out the exact values to change.
