  <p>it is basically saying <code>Request Timeout</code>, when all my start scripts are correct. The only thing it could be looking for is for me to define a port. The problem is, this isn't a nodejs app, its reactjs, so not sure what to do there.</p>
  <p>app set up:

  <p>please let me know if anyone has any suggestions.</p>
