WebSockets on OpenShift do not work with remote client

Question

I have a problem that I cannot solve. I implemented the ws-w630> js Websockets server on an opening cartridge using socket.io or WebSockets node js libraries. With any of them, the result is the same.

With the node js client running on the same platform with the opening platform, everything works fine.

When the client roams on my local computer, the client connects and disconnects suddenly, giving 1011 internal server errors.

I tried using other well-known clients, such as the echo service on WebSockets.Org or jsfiddle , but the result is the same, connect and disconnect unexpectedly.

I do not know why. Has anyone been able to connect to a remote WebSockets server from a remote server? The server is minimal and simple, and locally it works fine.

This is the code I'm using as a server:

var ipaddress = process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1";
var port      = 8000;

var app = require("express");
var server = require("http").Server(app);
var io = require("socket.io")(server);

var handleClient = function (socket) {
    // we've got a client connection
    socket.sendUTF("hello");
    console.log("connect");
};

io.on("connection", handleClient);

server.listen(port, ipaddress);

And this is the socket endpoint: WS: //js-camillorh.rhcloud.com: 8000

Thank!

Updated code after comment:

var ipaddress = process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1";
var port = process.env.OPENSHIFT_NODEJS_PORT || 8080;
var app = require("express");
var server = require("http").Server(app);
var io = require("socket.io")(server);

var handleClient = function (socket) {
    socket.sendUTF("hello");
    console.log("connect");
};

io.on("connection", handleClient);

console.log("listen: "+ipaddress+" "+port);
server.listen(port, ipaddress);

You bind to the wrong port, you need to bind it to 8080 as follows:

var port = process.env.OPENSHIFT_NODEJS_PORT || 8080;

Then you will continue to access your application using this URL:

ws://js-camillorh.rhcloud.com:8000

or for secure websites

wss://js-camillorh.rhcloud.com:8443
