BalenaCam Connection Always Fails, ValueError: ... does not appear to be an IPv4 or IPv6 address

Hi!
I just installed BalenaCam on my Pi3a+ today following every instruction correctly. However, every time I try connecting via my android or win10 PC (chrome), the page loads for a little bit, shows nothing, then shows connection failed. Interestingly, it did work instantly on Edge with using a regular mjpeg stream. What went wrong? How do I fix this? Is there a way (env variables?) to enable mjpeg by default? Please help, here are my logs :slight_smile:

Hello! So the issue I am seeing is ValueError: ‘aaf80f4b-a797-43bd-a41a-a383c76567e4.local’ does not appear to be an IPv4 or IPv6 address you can check this PR on how to disable IP hiding on webrtc on chrome here https://github.com/balenalabs/balena-cam/pull/62/commits/cc1e3669cf339eef51adf4dc094fd7be1067a312 .

Hi I get the same error when I try to connect via the web with Windows 10/Firefox. But I can connect with Windows10/Edge or with my Android/Firefox browser. Any hope of fixing this to play better with firefox on the pc?

Hello can you provide us the firefox version you are using? Also the issue will be solved if you disable ip hiding for webrtc connections on Firefox.

For those who come to this issue late, as I did, there’s a chrome extension called WebRTC Control that fixes it.
