Description

youtube-dl -J -flat-playlist -v  https://www.youtube.com/user/RedLetterMedia

This command used to work a couple of days ago without issue.
I'm using the same youtube-dl version (latest).
I've tested with different IPs on Mac and Linux.

I found this issue #1667
I tried running:

youtube-dl -J -flat-playlist -v --ignore-errors https://www.youtube.com/user/RedLetterMedia

looks like it throws the errors for all videos?

youtube-dl -J -flat-playlist -v -f 37/22/18/best https://www.youtube.com/user/RedLetterMedia

the command never exit

never mind, it was due to wrong syntax on my part
