Description

Today (May 22 2019) I started getting HTTP Error 503 messages when trying to download videos from Youtube.

The output pasted above resulted from running

youtube-dl -f 18 -4 -v https://www.youtube.com/user/ReviewTechUSA/videos?disable_polymer=1 --playlist-items 1

Only more recent videos seem to be affected, but I can't quite see the pattern. If, for instance, I run the same command with --playlist-items 4 instead that video downloads fine. Items 1-3 produce HTTP 503 errors though.

Also, I have ssh access to a remote computer on a different network that seems unaffected, which makes me think my IP is somehow being blocked, but apparently only for certain videos.

I am on the latest version as of this writing (2019.5.20) installed directly through pip.
