Issue setting up Pubnub Nodejs server

Question

Following the example from: https://www.npmjs.org/package/pubnub

I am trying to set up a connection from my nodejs server to pubnub via:

var pubnub  = require("pubnub").init({
    publish_key:    "pub key here",
    subscribe_key:  "sub key here",
    channel:        'my_channel',
    user:           'Server'
});  

pubnub.subscribe({
    channel: 'my_channel',
    callback: function(message) {
      console.log("Message received: ", message);
    }
});

pubnub.publish({ 
    channel   : 'my_channel',
    callback  : function(e) { console.log( "SUCCESS!", e ); },
    error     : function(e) { console.log( "FAILED! RETRY PUBLISH!", e ); }
});

// test msg to see if server connect to pubnub channel
function publish() {
  pubnub.publish({ 
    channel   : 'my_channel',
    message   : 'Server subscribed'
  });
}

I thought this followed the example provided but my server will not show up in the pubnub log nor receive any SocketIO events from the 2 peers trying to connect to each other. I am trying to use pubnub with SocketIO to send over ice candidates to establish p2p video via WebRTC

For peers that are trying to connect that are actually do have a pubnub connection working, the set up is as follows:

(function() {
  var pubnub_setup = {
    channel:       "my_channel",
    publish_key:   "pub key",
    subscribe_key: "sub key",
    user:          user
  };

  var socket = io.connect( 'http://pubsub.pubnub.com', pubnub_setup);

// various socket.on( ... )

})();

@jerryfox, there is a connection callback on subscribe called "connect". You should only issue your test publish on this "connect" callback... otherwise, you can publish before you've actually connected, and you'll never see the message. Try this:

pubnub.subscribe({
    channel: 'my_channel',
    callback: function(message) {
    console.log("Message received: ", message);
    },
    connect: publish
});
