Answer 1

This is how I solved it.
1 - open command prompt and type this:

ipconfig

Then copy paste your IPv4 Address eg ('182.167.2.65')

2 - Add the following line of code to your settings.py:

ALLOWED_HOSTS += '182.167.2.65'
CORS_ORIGIN_ALLOW_ALL = True # Change it in production and specify your own origins

3 - Run server as follows:

py manage.py runserver 0.0.0.0:8000

4 - In react now fetch to this direction:

'182.167.2.65' ## This direction is just an example (put your IPv4)
