Description

I use debian testing x64 and I was on youtube-dl 2019.06.21 when I noticed the issue yesterday afternoon. It was working as it should in the morning, so I assume soundcloud changed something in its site and broke youtube-dl.
I downloaded the newer version today and tested it on the same url, but it still fails to download. The previous one was also tested on 2 different arch installations and the result was the same.

I mainly use youtube-dl with mpv, like so
mpv --shuffle https://soundcloud.com/oneireuthslowbap
Mpv uses youtube-dl to scrape the site and play the content.

Thank you in advance.

Can you please write the reason for closing my issue report or what is it duplicate to?

---edit
Nevermind, got it. It is a duplicate of #21546.
I wrote the report down, and checked for existing ones, yesterday, but someone beat me to it 8 hours ago.
