[Answered ]-Django backend wont accept get requests from my front end

Following these steps worked for me:

1. Install Django CORS

   pip install django-cors-headers
   

2. Add it on INSTALLED_APPS (settings.py):

   INSTALLED_APPS = [
       ...
       'corsheaders',
   ]
   

3. Add it on the top of MIDDLEWARE (settings.py):

   MIDDLEWARE = [
       'corsheaders.middleware.CorsMiddleware',
       ...
   ]
   

4. The CORS variable can be this way (settings.py):

   CORS_ORIGIN_ALLOW_ALL = True
   # or: 
   CORS_ORIGIN_ALLOW_ALL = False
   CORS_ORIGIN_WHITELIST = (
     'http://localhost:3000', # or the reactjs address being used
   )
   

5. Clear webbrowser cache (Empty Cache and Hard Reload – for chrome) and restart the application.
