<p>I want to clarify that the app wasn't even starting, it was stuck at <code>starting your app</code>, I found this solution for that: <code>set MONGO_URL=mongodb://127.0.0.1:27017/sample</code> I now have a hunch that this might be what's conflicting?                                                                                                       </p>
