Error Django gives Bad Request 400 when DEBUG False

+1 vote

When I run the django server with DEBUG = True, it's running perfectly. But when I change DEBUG to False in the settings file, then the server stopped and it gives the following error on the command prompt:

CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False.

After I changed ALLOWED_HOSTS to ["http://127.0.0.1:8000",], in the browser I get the error:

Bad Request (400)

Is it possible to run Django without debug mode?

Hello @kartik,

With DEBUG = False in you settings file, you also need ALLOWED_HOST list set up. Try including ALLOWED_HOST = ['127.0.0.1', 'localhost', 'www.yourdomain.com']

Otherwise you might receive a Bad Request(400) error from django.

Hope it helps!

Thank You!

Tried this and it resolved all my problems.

ALLOWED_HOSTS = ['*']

When ALLOWED_HOSTS is set to '*', it matches every host so you don't have to guess what you could have missed out.
