@jasper That has happened to be several times. The solution every time: update my installation.
@MOTT it's up to date on Arch Linux, 2019.09.01-1
For instance this one https://www.youtube.com/watch?v=ij0y_nf-avQ it says video is not available after "Downloading video info webpage".
It doesn't seem to be the captcha wall or something..
@jasper Did you figure it out? I was unable to download it either.
It seems that you can still download it on invidious: https://invidio.us/watch?v=ij0y_nf-avQ
@MOTT i figured there would be a further update in youtube-dl upcoming, though didn't check their site for it.
But then i just tried again with the current version of youtube-dl and it worked? I am not sure what changed.
Maybe the VPN exit? But the browser could watch it. But have noticed that one browser setup was behind the captcha wall, and another wasn''t, on the same VPN. It might be that picky..
