Troubleshooting
Check the short path first: room key, network reachability, then OBS source state.
Guest cannot connect
Create a fresh room, resend the guest message, and confirm that the relay hostname and port are reachable from the guest network.
Host receives no audio
Confirm the peer card shows packet activity, then use Re-add to current scene and check the OBS audio mixer.
Audio quality is wrong
Keep OBS at 48 kHz stereo, verify the selected processed OBS track, and use the L/R test before going live.
