socket.io和redis，节点js不能在宅基流浪盒上的laravel中工作

i am using node js, socket.io and redis for publish some message in html view. but it's not working. when i use simple localhost installed laravel , it's working fine, i did not understand why it's happening with vagrant installed laravel. i share my code, please help.

server side server.js file

var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io').listen(server);
var redis = require('redis');

server.listen(3000);
console.log('server listening 3000');

io.sockets.on('connection', function (socket) {

console.log("new client connected");
var redisClient = redis.createClient();
redisClient.subscribe('message');
console.log("redis start");

redisClient.on("message", function(channel, message) {
    console.log("mew message in queue "+ message + "channel");
    socket.emit(channel, message);
  });

  socket.on('disconnect', function() {
    redisClient.quit();
    console.log('redis disconnected!');
  });

 });

Client Side

    <script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
    <script src="https://cdn.socket.io/socket.io-1.3.4.js"></script>

      <script>
        var socket = io.connect('http://localhost:3000');
        alert('connection');
        socket.on('message', function (data) {
            $(".progress-bar").css('width',+data+'%');
            alert('connection established');
            $("#messages").append( "<p>"+data+"</p>" );
        });
     </script>

Controller

    class SocketController extends ApiController
    {
         public function testview(){
         return view('courier.socket');
     }

     public function send_message(){
       $count = 90 ;
       for ($i = 0; $i < $count; $i++) {
        Redis::connection();
        Redis::publish('message',$i);
       }
      return 'done';
    }

 }

all above code working fine with simple localhost installed laravel 5.2, but it's not working with homestead vagrant box laravel.
