WebSocket connection to OpenShift app failed

Question

I created an app with NodeJS and I'm using ws module. If I test the app in localhost it works and there isn't any problem to connect websockets. Now I've upload the app to Openshift and when I try to access from the client it returns that is not possible to stablish a connection to the websocket.

If I do a tail in putty to my app I have this message: DEBUG: This type of response MUST NOT have a body. Ignoring data passed to end().

The code that I have in the server is:

#!/bin/env node

//Openshift variables
var ipaddress = process.env.OPENSHIFT_NODEJS_IP || "192.168.69.42";
var port = process.env.OPENSHIFT_NODEJS_PORT || 8080;


//NodeJS require modules
var Enum = require('enum');
var WebSocketServer = require('ws').Server
    wss = new WebSocketServer({host:ipaddress, port:port});
var fs = require('fs');


wss.on('connection', function(ws) {
    console.log((new Date()) + ' Connection from origin: ' + ws._socket.remoteAddress);
});

console.log((new Date()) + " Server is listening on: " + ipaddress + ':' port);

And in the client:

var ws = new WebSocket("ws://192.168.69.42:8080/");

ws.onopen = function() {
    console.log("Connected.");
    ws.send("This is the client speaking.");
};
