WebRTC problem with Chrome

[Lionel]

Hello,

User for several years of version 1 (user very happy), I installed a new server with the 2.2-beta (using the script bbb-install.sh, very good job).

However, I am having a connection problem for the audio and microphone with chrome (error 1006). With Firefox no problem.

I tested with multiple networks, always the same problem.

The test.bigbluebutton.org however works with my browser.

I installed a STUN server (https://docs.bigbluebutton.org/2.2/setup-turn-server.html) but the problem is still present.

Result of bbb-conf --check (the external_rtp_ip and external_sip_ip parameters do not have the URL of my STUN server, is this normal?). I changed the url by myurl and ip by myip for this message:

A 1006 error is pretty rare. To debug I'll need the full browser console logs (F12). I'll also need the server logs to cross reference.

The steps to get the server logs are:

1. Join with a unique name
2. Try to join audio and wait for failure
3. grep "<your_username>" /opt/freeswitch/var/log/freeswitch/freeswitch.log
4. Copy the sessionId at the start of the line
5. grep <sessionId> /opt/freeswitch/var/log/freeswitch/freeswitch.log > failed-session.log

If you could send me the browser console logs and freeswitch logs I can take a look and see if anything sticks out. It would also be good to have the Firefox logs to have a comparison.

[Lionel]

I sent the logs by email.

Thank you.

Sorry, I found the problem.

This is the TorGuard VPN Extension for Chrome.

However, it is strange, the error 1006 appears when the application is activated even if the proxy is inactive.

Proxies usually don't play well with WebRTC unfortunately. I noticed in the failed logs that the browser was sending no candidates and FreeSWITCH will reject those every time because there's no chance of it working. I would have to compare with the logs from our test server, but it could be that our server worked because the relay (TURN) candidate was generated and selected. There could also be a configuration issue with the STUN server that you used because I noticed that the Firefox logs only included private IPs so STUN didn't work.
