Only works on same network about signalrtc

I had the same problem, it worked only on local network. But then I add Google STUN server, this fixed problem.

var servers = { 'iceServers': [{ 'urls': 'stun:74.125.142.127:19302' }] };
 //var  _iceServers = [{ url: 'stun:74.125.142.127:19302' }], // stun.l.google.com - Firefox does not support DNS names.

Still doesn't seem to work. Also doesn't work on your website https://signalrtc.com
Could you try adding a TURN server in your code. You can create one on numb.viagenie.ca for free.

It didn't seem to help in my solution but maybe it does in yours.

Added something like:
var servers = { iceServers: [ { 'urls': 'turn:numb.viagenie.ca', 'credential': 'xxxxx', 'username': 'xxxxxx' } ] };

Are you sure site doesn't work? I didn't check long time, will check first.

Yes, vidéocommunication doesn't work, will look at this on weekend. Or you can try yourself.
