#31092 closed Bug (duplicate)

Django 3 runserver command stops after login into admin page

Reported by: Alejandro Otero Ortiz de Cosca Owned by: nobody
Component: Utilities Version: 3.0

The Django 3 development server halts when login into the admin page. The dev server (runserver) serving a blank (straight after running startproject) project responds fine to the welcome page and the admin login form page, but it crashes when redirecting after a successful login.

  • The dev server starts without errors or warnings.
  • All requests are responded correctly (base endpoint and admin login page).
  • Login request seems to be processed correctly, client gets the 302 redirection to the admin page after login.
  • Server stops working without printing any error.

I have created a new virtualenv with Python 3.8 and I can login to the admin page without any problem

This seems like a duplicated of issue #31067 which should be fixed by upgrading your Python version to the latest supported version in the 3.7 branch (3.7.5 I think).

Please reopen if that's not the case, thanks.
