Troubleshooting "There was a problem connecting the video call." errors

I am able to initiate a call, and get the two screens (one black, and other smaller black on top right corner). It stays like that for a few seconds and then says the call has ended. I couldn't get any audio or video through. Can we have debug messages for WebRTC stuff going on in the background?

1. I am running my own Janus WebRTC gateway, with config files used from the vagrant image. I am not running my own STUN/TURN but using google's and turn from viagenie.ca using my credentials
2. I'm running Version: 3.5.0 (3.5.1) and Database: postgres
3. Both using Web Apps in Chrome 55
4. Not tested
5. It is repeatable on every call.
