Socket.IO with Cordova not working on Device

I'm currently developing an Apache Cordova app with Ionic Framework that should communicate through a WebSocket and I use the Socket.Io library for it. Now when I run it on my desktop browser everything works fine but when I build for Android and test it on my Smartphone it doesn't work.

My Server looks like this:

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

server.listen(8200, '192.168.0.127', function() {
  console.log('Server listening...');
});

io.listen(server);

io.on('connection', function(socket) {
  socket.emit('init', data);
});

And since Ionic is friends with AngularJS my Client Controller looks like this:

.controller('AppCtrl', function($rootScope, $scope, ServerUrl) {

  var socket = io.connect(ServerUrl.serverUrl()); // ServerUrl: 'http://192.168.0.127:8200'

  socket.on('init', function(data) {
    // something
  });

I included the Socket.IO Client script in my index.html head like this:

<script src="lib/socket.io/socket.io.min.js"></script>

When I remote debug the app it throws this repeatedly with different t parameters:

Failed to load resource: net::ERR_ADDRESS_UNREACHABLE     http://192.168.0.127:8200/socket.io/?EIO=3&transport=polling&t=1431079993172-0

I've thoroughly searched every related question on here but they didn't solve my problem. I really need this thing to work and would appreciate any help.

Thanks in advance.
