Details

Django Project Foundation team made some changes in security requirements for all Django Version 4.0 and Above. In Which they made mandatory to create an list of urls getting any type of form upload or POST request in project settings named as CSRF_TRUSTED_ORIGINS.

They did not updated the details in latest tutorial documentation but they published the Changes Notes at https://docs.djangoproject.com/en/4.0/releases/4.0/#csrf-trusted-origins-changes-4-0.

First Solution

For localhost or 127.0.0.1.

Goto settings.py of your django project and create a new list of urls at last like given below

if Your running an project in localhost then you should open all urls here * symbol means all urls also there is http:// is mandatory.

Copy the list of ALLOWED_ORIGINS into CSRF_TRUSTED_ORIGINS like given below.

ALLOWED_ORIGINS = ['http://*', 'https://*']
CSRF_TRUSTED_ORIGINS = ALLOWED_ORIGINS.copy()

Third Solution

When Deploying you have to add urls to allow form uploading ( making any POST request ).

I Know this maybe tricky and time consuming but it's now mandatory.

Also this is Mandatory to Online IDEs also like Replit, Glitch and Many More.
