Description

I can't describe much more than what is written above. I'm not located in Germany, but I get the same error with a slightly older ytdl version from a machine that is located in D, so I don't think this is a geoblocking issue.

I suspect that this is https://github.com/yt-dlp/yt-dlp/issues/7666, but the withdrawn API is now getting 404 (no idea what you mean) instead of 410 (used to know this but not any longer).

[lnw]

Could be. There are some differences and I don't know the underlying structure enough to say whether it is the same underlying issue.

Whichever issue at yt-dlp it was, back-porting the latest master fixes the problem:

Indeed, the yt-dlp master (069b2aeda) works!
