[Python] "Error 404: The resource is not found on this computer" when deploy Django Web...

I have a Django web application that works great when testing it in local server. It uses generics.APIViews, and there is no index.html file and no static files to be served.

I've read and abided by all the Render.com docs to deploy to Render.com including https://docs.render.com/deploy-django and https://docs.render.com/web-services#port-binding.

I suspect it has something to do with port binding. Been researching different ways to make it work. I'm new to Django so probably something simple I'm missing:

Below a shot of my settings.py:

import os
import dj_database_url

BASE_DIR = Path(__file__).resolve().parent.parent

# SECURITY WARNING: don't run with debug turned on in production!

ALLOWED_HOSTS = ['*']

RENDER_EXTERNAL_HOSTNAME = os.environ.get('RENDER_EXTERNAL_HOSTNAME')
if RENDER_EXTERNAL_HOSTNAME:
