Description

WRITE DESCRIPTION HERE
It appears that something with either youtube.com or youtube-dl has stopped working as expected. Anyway, thank you for looking at this.

[SolidTux]

I can confirm that the same happens for me under Fedora 31 with youtube-dl 2020.03.08.

You must authenticate for age-gated videos.

I have the same issue and fixed by running

youtube-dl --rm-cache-dir URL
