No response

Provide a description that is worded well enough to be understood

Probably a "regression" issue because it works on previous releases

Original reported on JunkFood02/Seal#878 by @ayesc9000

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)

Regression caused by db3ad8a

I'll make a quick-fix release soon. Till then, if you cannot use nightly, use --netrc-cmd "" as workaround.

FYI. Vimeo has this issue too as shown in my https://www.reddit.com/r/youtubedl/comments/14fddtl/unable_to_download_this_vimeo_video_on_two/ post. I was told this issue was related to this bug.
