socket.io cannot communicate with back-end through express

I am using socket.io for fetching some data from the express app. Everything works fine on localhost:8080 but when i deploy my code to the server, client side socket.io cannot communicate with back-end socket.io through express server. I've an apache on the server that forwards everything to localhost:8080 including domain.com/socket.io/?transform=polling... and it extends the request to the express server but express returns a 404 (it comes from the express, not from apache). I am out of ideas, what could be the problem? Here is my code:

express = require "express"
jade = require "jade"
fs = require "fs"

class Bootstrap
 _self = undefined
 routes:
   DEFAULT_PATH: "/"
   TEMPLATE_PATH: "/load/:view"
   DIRECTIVE_PATH: "/directive/:template"
 options:
   templatePath: "#{__dirname}/../src/templates"
   isDev: "#{__dirname}/../dev"
 contentPath: "#{__dirname}/../frontend"
 libraryPath: "#{__dirname}/../bower_components"
 port: 8080
 status:
   notFound: 404
 isDev: undefined

 constructor: ->
   _self = @
   @isDev = fs.existsSync @options.isDev
   @app = express()

   @app.use "/frontend", express.static(@options.contentPath)
   @app.use "/bower_components", express.static(@options.libraryPath)
   @app.set "views", @options.templatePath
   @app.set "view engine", "jade"
   @app.engine "jade", jade.__express

   @app.get @routes.DEFAULT_PATH, (request, response)->
     appData =
       data:
         isDev: _self.isDev
     response.render "index", appData
   @app.get @routes.TEMPLATE_PATH, (request, response)->
     view = request.param "view"
     response.render view
   @app.get @routes.DIRECTIVE_PATH, (request, response)->
     template = request.param("template").replace ".html", ""
     response.render "directives/"+template
   @app.use (request, response, next)->
     _self.logger.warning "404 Not Found!: " + request.originalUrl
     response.status(_self.options.status.notFound)
      appData =
        data:
          isDev : _self.isDev
          request: request
      response.render "404", appData

   @server = @app.listen @options.port
   @io = require("socket.io").listen @server

   @logger = require("./logger.js")
   @logger.init @isDev

   @socketConnector = require("./live.js")
   @socketConnector.init @io

   @

new Bootstrap()
