Why can’t I use my ID and password to log in?

Patreon.com and courses.macmost.com are two completely different, unrelated sites.

If you are trying to log in to courses.macmost.com with your Patreon ID and password, or you are trying to log into Patreon with your courses.macmost.com ID and password, note that these are different sites. Creating an account at one, does not create an account at the other.
