First Heroku deploy failed `error code=H10`

Question

I deployed my app to Heroku. It's a node.js + express + socket.io app and this is the package.json file

{   "name": "game_test",   "author": "Ilya",   "description": "A test app for our board game",   "version": "0.0.1",   "private": true,   "scripts": {     "start": "node app"   },   "dependencies": {     "express": "3.0.6",     "jade": "*",     "socket.io" : "*"   },  "engines": {       "node": "0.8.14"   } } 

This is the log I get:

heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=game-test-1.herokuapp.com fwd=37.26.146.185 dyno= queue= wait= connect= service= status=503 bytes= heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/favicon.ico host=game-test-1.herokuapp.com fwd=37.26.146.185 dyno= queue= wait= connect= service= status=503 bytes= 

What does it mean?

Found solution for me here: Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)

In my case my app crashed because I was hard setting the PORT, instead of using the port that heroku dinamicaly sets, which can be accessed with process.env.PORT

app.listen(process.env.PORT || 3000, function(){   console.log("Express server listening on port %d in %s mode", this.address().port, app.settings.env); });
