First, you should run heroku logs to get logging output.

Second, do you mean to have commented out listen on your server? Without this, your server won't allow any incoming connections:

// http.listen(3000, function(){ // console.log('listening on *:3000'); // });

Finally, instead of binding to a hardcoded port (3000), you should bind to an environment variable with a default:

http.listen(process.env.PORT || 3000, function(){ console.log('listening on', http.address().port); });
