Typical reasons for broadcast termination could be connectivity issues or audio/video source issues.
Network is behind a firewall or VPN
Network disconnects occur: may happen on WiFi environments with multiple hotspots
A Chrome extension is blocking some network activity (AdBlock, popup blocker)
A web security software (Norton, AVG, etc.) is blocking loola.tv from operating properly
There's no audio source selected, or the audio source is invalid.
A virtual camera source fails to send a constant video stream to the browser
Wrong Encoder settings in RTMP mode:
For example: the H264 profile is set to "high" instead of "main"
Solving Connectivity Issues:
Make sure no firewall, Chrome extension, or other software is blocking network activity. Specifically, AdBlock and other popup blockers are known to cause issues.
Run the following connectivity test: https://test.webrtc.org/?turnURI=turn%3Aturn.loola.tv%3A80&turnUsername=janususer&turnCredential=januspwd&stunURI=stun%3Aturn.loola.tv%3A80
(results should look like this):
3. Try switching to a wired connection
Solving Video/Audio issues:
If you are using a virtual camera device, retry broadcasting with the build-in webcam or a physical USB webcam. If It solves the broadcast disconnects, then the issue may be in the virtual camera driver.
Try changing the audio source.
