Description

I have been facing this issue recently that whatever course from udemy I am downloading.. it always downloads a first few vids and that crashes with 403: Forbidden ...

I tried to run the youtube-dl as simply as:

youtube-dl https://udemy.com/apache-kafka/ --cookies ./../cookies.txt --verbose

but still no luck ... what I noticed is that first files reside in udemy.com and the failing one is in knowband-asset-bucket.s3.amazonaws.com ... could that be the problem?

another course having the same issue

https://udemy.com/microservices-with-node-js-and-react

UDemy has changed their videos. They are now DRM protected. It's pretty much useless. They started doing this about Mid March 2021 :(. They are going to lose a few hundred dollars from me each month now.

that sux ... any idea on if this could be bypassed? or that'd be a legal issue so no fix in sight?
