I'm trying to deploy a Flask app to Heroku however upon pushing the code I get the error 

2013-06-23T11:23:59.264600+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

I'm not sure what to try, I've tried changing the port from 5000 to 33507, but to no avail. My Procfile looks like this:

web: python main.py

main.py is the main Flask file which initiates the server.

Thanks.

heroku flask
