Hi. My balenacam is not working. When I try to access the WebRTC stream, everything but the stream itself loads. I can double-click to go fullscreen etc - but no video. The camera and RPI 3 A+ is confirmed working.

From the logs - the only weird thing is the .local address instead of the IP my computer is on?

Looks like some sort of Bonjour-related problem? Also tested on my Cellphone wifi sharing, to remove Bonjour from the equation. Same problem

@aweussom balenaCam doesn't work with mdns adresses. In order to disable them see here https://github.com/balenalabs/balena-cam#additional-information. If you are on chrome and you can't find the flags see https://github.com/balenalabs/balena-cam/issues/83 .

That option is not available in my Chrome. I blocked mDNS with the windows 10 firewall, and that worked fine: [In a dministrator powershell]

Set-NetFirewallRule -DisplayName "Google Chrome (mDNS-In)" -Enabled True -Action Block
