Description

Udemy Paid Course, youtube-dl can download the first video, but failed with ascendant videos(2, 3, ...).

I have searched the bugtracker for similar issues, but most of them are still open, the closed ones don't help to resolve the problem. So escalate this issue again.

From the log, your command was s/t like:

youtube-dl --download-archive --verbose machine-learning-data-science-foundations-masterclass.txt --playlist-start 1 -R infinite --fragment-retries infinite -c -w -o './Video/%(playlist)s/%(chapter_number)s - %(chapter)s/%(playlist_index)s %(title)s.%(ext)s' --cookies cookies.txt --verbose 'https://www.udemy.com/machine-learning-data-science-foundations-masterclass/learn/'

yt-dl thinks you are trying to download the archive index: remove the first --verbose.

When you do that you will most likely reproduce #29925, or one of the other issues with Udemy (#29410, #29705). #29925 explains why the extractor is unlikely to be fixable.

So, as above, you have duplicated #29925.
