What port to use on heroku python app
问题 So I have created 2 iOS apps (One sends coordinates, one receives them) and a python server. One of the apps sends GPS coordinates to my python server that is hosted on heroku. The server will then emit the received GPS coordinate to the OTHER iOS client app that will drop an Apple Maps pin on the received coordinate. The project works perfectly while testing on local host with any specified port. However when I have migrated the server to Heroku I was receiving this error The error occurs
