Bug Report [Site Support]

The udemy course (downloading the playlist/video course) is a paid course, which i download by providing my login credentials (-u user@email.com -p passphrase) for the ID i have bought the course with. I have successfully downloaded some of the course video (same one) before but couldn't complete it due to time constraints.

Description

The issue seems to be a failure to either download the login page or to post the login credentials, possibly due to changes to the site or any changes made to how youtube-dl manages to login using the passed credentials. I don't believe my login credentials would be required but I'll provide cooperation if needed.
