WebRTC does not work on different network/cellular data

I am facing a problem. I can connect by webrtc in local network (using wifi), but not being able to connect to different netowrk. How can I solve this problem?

new RTCPeerConnection({
    iceServers: [
      { urls: "stun:stun.l.google.com:19302" },
      { urls: "stun:stun1.l.google.com:19302" },
      { urls: "stun:stun2.l.google.com:19302" },
      { urls: "stun:stun3.l.google.com:19302" },
      {
        url: 'turn:numb.viagenie.ca',
        credential: 'muazkh',
        username: 'webrtc@live.com'
      }
    ]
  });

Solution

  • By the logs you provided I can tell your turn server is not accessible as there are no relay candidates on both ends.

    The easiest way to check it is via trickle ice page. It might be that you use a wrong port, made a typo in credentials or that the server is not responding.
