Description

The udemy download function doesn't work anymore, I'm using the cookie authentication. The message at the end is: Course 10543 is not free. You have to pay for it before you can download. Use this URL to confirm purchase: https://www.udemy.com/cart/checkout/express/course/10543/

Can I add that using user and password option are not working either. Please see below (I've purchased the course with the credentials I'm giving to youtube-dl):

I'm running latest (2020.09.14) version on a Synology NAS with Linux-4.4.59+-x86_64-with-glibc2.2.5

Thanks!

This is a known issue unfortunately, search other bugs about udemy and you'll find a couple very similar. udemy has changed the page format, there's no way to circumvent this with any argument or modified link (like removing /course/), youtube-dl's udemy extractor is searching using a regex that is not valid any more, and also some links used to search have been changed, resulting in the errors above (page not found, or the course is not free, etc)

Same here, BTW cookies are not working as well. Maybe we can borrow some code from https://github.com/r0oth3x49/udemy-dl?
