Django MemcacheUnexpectedCloseError and [WinError 10061] No connection could be made because the target machine actively refused it

Hi I am new at django and trying to use django-cache to speed up page load that will list out 100 companies and their details per page but I am constantly running into errors. When I use the IP and Port from the django doc 127.0.0.1:11211 I get this error:

Please let me know if anything more is required to answer this question.

1. You've configured your cache backend to use a Memcached server at 127.0.0.1:8000. That's likely a misconfiguration, since your Django development server would run at 127.0.0.1:8000 by default. The default port for Memcached is 11211 – you might want 127.0.0.1:11211.
2. Have you downloaded Memcached and started it? Are you sure there's a Memcached instance listening?
