WRITE DESCRIPTION HERE
Since few days, I'm not able to download playlists on youtube.
Error message is:
ERROR: Unable to download JSON metadata: <urlopen error [Errno 111] Connection refused> (caused by URLError(ConnectionRefusedError(111, 'Connection refused'),))
I'd tested on my config (linuxmint tricia) and on a manjaro vbox machine but the result is the same...

Network issue on your side.

Network issue on your side. really strange because I’m able to download with mps-youtube… and why this affects only playlist?
