title: Deploying Flask with Heroku
body: <p>I'm trying to deploy a Flask app to Heroku however upon pushing the code I get the error </p>
  
  <pre><code>2013-06-23T11:23:59.264600+00:00 heroku[web.1]: Error R10 (Boot timeout) -&gt; Web process failed to bind to $PORT within 60 seconds of launch 
  </code></pre>
  
  <p>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:</p>
  
  <pre><code>web: python main.py 
  </code></pre>
  
  <p><code>main.py</code> is the main Flask file which initiates the server.</p>
  
  <p>Thanks. </p>
