🔍 Troubleshooting

No camera permission prompt? Check browser settings - camera might be blocked
Connection failed? Ensure signaling server is running: docker ps | grep signaling
No video from reception? Check go2rtc is capturing from /dev/video0
Audio issues? Check microphone permissions and system audio settings
Firefox using camera? Close Firefox tabs that might be using /dev/video0
