Failed to login to django admin page with valid username and password

EDITED:

I hosted a site on amazon AWS with a domain ( www.abc.com ).

First: I tried to log in to the django admin site, but redirected it again to the same page without showing any errors (Note: username and password are correct)

Second: After successful registration, try logging into the django homepage with a username and password: It will redirect to the same login page by adding the next keyword between the URLs.

http://www.abc.com/login/?next=/employee/jcbdfvdhdfhvhdfsvsdhfhb-super-admin/home/dashboard/

Found after researching servers:

I stopped all applications like wsgi, suprervisorctl, ngnix etc. and then run the following command on the ec2 aws (Terminal) console

 python manage.py   xxx.xx.xx.xx:8000

. xxx.xx.xx.xx - (www.abc.com) IP
