Description

Trying to download the YouTube members only video, and unable to download the video. I’m currently a member of the channel, and able to watch the YouTube video at the website. I downloaded the most recent cookies and applied it on the script.

I’m able to download the other videos that do not require “members only” using Youtube-dl. I was able to download the members only video about two weeks ago without a problem.
