what even is HTTP Error 567: Unknown Status, yt-dlp bilibili downloads all fail

[Obnoxious Oranguta]

bilibili through yt-dlp now dies on a 567, which isnt even a real http code lol. only the bilivideo cdn urls, the akamai ones go through

[download] Got error: HTTP Error 567: Unknown Status. Giving up after 10 retries

 

[The Hunt For t]

Adding a Range header gets around it for now: --add-headers "Range:bytes=0-". The bilivideo backup hosts apparently want Range plus a proper user agent and referer. Nothing merged into yt-dlp yet, the PR is still open.
