H14 Heroku No web processes running for Flask, Python
I solved the problem by removing Procfile and re-creating it. Git for some reason did not recognize this Procfile and named it something like Pro/143/file (I don't know why).
So, if you encounter such a problem, try to re-create your Procfile. Anyway, it helps for me.
P.S I left the contents of the file as before: web: gunicorn app:app.
As you can see, everything works:
How to fix ' code=H14 desc=No web processes running ' error on flask heroku app
Usually it is either
- Heroku does not know which web process to start. This is fixed with Procfile.
Procfile:
web: python myServer.py
- Web process is not listening to right port. This is fixed by web server start 6 environment configuration
Get the right port from PORT variable:
port = int(os.environ.get('PORT', 5000))
