Have you done any investigation of the ICE/STUN or DTLS negotiations? Have you consulted the browser Javascript console to see if anything sticks out?

If you are going to use WebRTC seriously in any fashion these are things you need to learn and dig into. There are a lot of moving parts outside of Asterisk that can cause problems.

As for the “Error sending STUN request” message that is generally harmless - it usually occurs when you don’t have IPv6 but it is trying an IPv6 path.
