I've deployed succesfully but when I run my app I get this error in my browser.

These are what my heroku logs says:

What mistake am I doing?

-------EDIT-------

app.js file

var app = require('http').createServer(handler)
, io = require('socket.io').listen(app)
, fs = require('fs')

function handler(req, res) {
    if ('GET' == req.method && '/images' == req.url.substr(0, 7) && '.jpg' == req.url.substr(-4)) {

            if (err || !stat.isFile()) {
                res.writeHead(404);
                res.end('Not Found');
                return;
            }

What's up?

Your process takes too long to start up. Hard to say without looking at your code, but I am guessing you are not binding to the right port. Are you listening on the port specified by the environment variable PORT? That's how Heroku detects when you have finished "starting up".
