I am trying to deploy my application to Heroku.

The build succeeded but there is an application error.

Here is the build log:

2017-08-19T10:52:32.433135+00:00 heroku[web.1]: State changed from crashed to 
starting

2017-08-19T10:52:20.000000+00:00 app[api]: Build succeeded

MongoClient.connect with auth credentials.

Really hope someone can point me in the right direction. Thanks.

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);
 });
