WebRTC Ice State = "failed" black Video

Question

in about:webrtc in firefox my IceState is always "in progress" until it fail. If i use the website in local it works, but if a friend try to call me it doesn't work the remote starts but it's blank.

my turn stun server:

{ "iceserver":{url:'stun:stun01.sipphone.com'},
{url:'stun:stun.ekiga.net'},
{url:'stun:stun.fwdnet.net'},
{url:'stun:stun.ideasip.com'},
{url:'stun:stun.iptel.org'},
{url:'stun:stun.rixtelecom.se'},
{url:'stun:stun.schlund.de'},
{url:'stun:stun.l.google.com:19302'},
{url:'stun:stun1.l.google.com:19302'},
{url:'stun:stun2.l.google.com:19302'},
{url:'stun:stun3.l.google.com:19302'},
{url:'stun:stun4.l.google.com:19302'},
{url:'stun:stunserver.org'},
{url:'stun:stun.softjoys.com'},
{url:'stun:stun.voiparound.com'},
{url:'stun:stun.voipbuster.com'},
{url:'stun:stun.voipstunt.com'},
{url:'stun:stun.voxgratia.org'},
{url:'stun:stun.xten.com'},

And i'm using an AWS server as STUN and signaling. in about:webrtc errors:

INFO setting pair to state FAILED ERR specified too many components WARNING specified bogus candidate ERR pairing local trickle ICE candidate srflx

Answer 1

Your setup seems to require TURN and you have not provided working TURN servers.

By having ten stun servers, you're trying to get an opinion about your public IP address from ten different people. The answer won't change. Just use a single STUN server...

Using other people's TURN credentials is not something you should do without permission. If you test the credentials using http://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ you will notice that you don't get relay candidates. For turn:numb.viagenie.ca the credentials are incorrect and 192.158.29.39 doesn't seem to be running a TURN server anymore.
