Cannot connect to node externally

I am currently trying to connect to a local server and have node run an app on port 8080. I have node and apache installed. When apache is switched on I am able to connect to the apache server externally. However when node is running and apache is stopped I cannot connect externally. I can however connect locally to node even when apache s running. Here is the code I am using:

var express = require('express');
var app = express();

var mysql = require('mysql');


var connectionpool = mysql.createPool({
    host: '127.0.0.1',
    user: 'root',
    password: '',
    database: 'development',
    port: 3306,
    connectionLimit: 50
});
var UAParser = require('ua-parser-js');
var bodyParser = require('body-parser');

app.use(express.static(__dirname + '/public')); // set the static files location /public/img will be /img for users
app.use(express.logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
    extended: true
})); // pull information from html in POST                       // pull information from html in POST


require('./config/signup.js')(app, express, connectionpool, UAParser);

//Setup for external access

var http = require('http');


var server = http.createServer(app).listen(8080);

console.log('Rest Demo Listening on port 8080');

Any help would be greatly appreciated. I actually had it connecting externally yesterday evening briefly.
