peerjs/webrtc iceConnectionState failed

问题

I've been trying to figure this out for a while. I'm trying to establish a simple connection using peerjs. I can connect successfully to the peer with id USER_ID. However, they are unable unable to connect to me. I receive the following log when they try to connect.

iceConnectionState is changed to failed eventually and no data can be recieved.

The application is using the peerjs cloud server
I'm using the latest version of Chrome. They have tried using latest versions of Chrome and Firefox
They have switched off any firewalls
Have even tried the peerjs chat example and it fails with the same error.

Any idea why this might happen / going on here?

Any help appreciated!

I had the exact same issue. Adding the STUN TURN servers should resolve the issue.

Client Side Code

peer = new Peer(this.api.currentUserValue().id+'-'+this.api.currentUserValue().first_name,{
                                                    host: 'localhost',
                                                    port: 8080,
                                                    path: '/api',
                                                    debug: 3,
                                                    config: { 'iceServers': [
                                                      { 'url': 'stun:stun.l.google.com:19302' },
                                                      { 'url': 'turn:numb.viagenie.ca',credential: 'xxxx', username:'xxxx@gmail.com'  } ] } // this is must for keeping the connection open
                                                      });

Server Side code

var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io')(server);
var expressPeerServer = require('peer').ExpressPeerServer;
var path = require('path');



app.set('port', (process.env.OPENSHIFT_NODEJS_PORT || "8080"));
app.set('host', (process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1"));

app.use(express.static(path.join(__dirname, '/client')));
app.use('/api', expressPeerServer(server, {debug:true}));




server.listen(app.get('port'),app.get('host'),function(){
  console.log('Server running at %s:%s',app.get('host'),app.get('port'));
});
