WebRTC Not Working For Video Calls

We have setup Rocket.Chat to utilize a hosted STUN/TURN server per the instructions of that page. When we click to start a video chat, nothing happens.

Any advice or guidance would be greatly appreciated.

Thank you,

Hello. We have the same problem. How did you solve it?
