Django DEBUG False not working in the Production Environment - django

Question

I am new to Django and Python world, I am currently working on an Dajngo site, which is hosted on a Ubuntu20.04 VM. Upon hosting the site to the production, I noticed that, although the DEBUG is set to False in the prodiuction settings. I still see the Django DEBUG erros as if the DEBUG is set to True .
When I run python manage.py runserver command on the VM I get the below error.
CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False.

I have carefully reviewed the settings code to see if the DEBUG is True in any part of my code but everything looks good.
Please help

Answer 1

You need to ALLOWED_HOSTS variable in settings.py.
ALLOWED_HOSTS = ['your_domain.com','www.your_domain.com']
or, this will allow all the domain which is not recommended
ALLOWED_HOSTS = ['*']

Answer 2

I am also having the same issue however I am using the .env file to manage the settings.
settings.py # my settings file
DEBUG = env('DEBUG')
.env # my .env file
DEBUG=False
the app works exactly as intended except for for the debug part, by the way the app hosted on ubuntu 20.04
