Django Origin checking failed does not match any trusted origins.


If you came across this error on Django e.g. when trying to log into the admin

Origin checking failed - https://david.dev does not match any trusted origins.

In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django’s CSRF mechanism has not been used correctly. For POST forms, you need to ensure:
Your browser is accepting cookies.
The view function passes a request to the template’s render method.
In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL.
If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data.
The form has a valid CSRF token. After logging in in another browser tab or hitting the back button after a login, you may need to reload the page with the form, because the token is rotated after a login.

It means that you are probably running Django 4 without CSFR trusted origins in your settings.py file so all you have to do is add this line:

CSRF_TRUSTED_ORIGINS = ['https://*.yourdomain.com']
