I don't have the reputation to reply to the correct comment, but for me the issue was that I didn't have the run.gunicorn.sh file in my root directory, this resulted in the same "No web processes running" error.

If you don't have this file, create it with contents:

gunicorn -b :5000 --access-logfile - --error-logfile - build:app

Where 'build' is the name of your python file (build.py in this case) and app is the name of your app in the code.

Also make sure that gunicorn is included in requirements.txt, like others have already pointed out.
