OpenTok - Subscriber failed to subscribe to a stream in a reasonable amount of time

I am implementing a Network Test for my Web-application using OpenTok's js library.

To do that, I create a publisher, connect to session, then make a subscriber connect to the publisher's stream.

The Test is working on other browsers (I have tested Chrome and Internet Explorer) but on Firefox version 57.0.1 I get an error - 'The stream was unable to connect due to a network error. Make sure you have a stable network connection and that it isn't blocked by a firewall.'

Solution

  • Make sure when you create the OpenTok Session you are using a 'routed' Session, not a 'relayed' one. Also make sure you are passing the 'testNetwork' property to the subscribe method. Here is a working sample:

    // Sample code
var session = OT.initSession(APIKEY, SESSIONID);

session.connect(TOKEN, function(err) {
  if (err) {
    alert(err.message);
    return;
  }
  var publisher = session.publish();
  publisher.on('streamCreated', function(event) {
    session.subscribe(event.stream, null, {
      testNetwork: true
    }, function(err) {
      if (err) alert(err.message);
    });
  });
});
