USA

### Provide a description that is worded well enough to be understood

When trying to download any livestream on youtube, I get an error that says `Failed to download m3u8 information`, with an `HTTP Error 404: Not Found`

I had a somewhat similar issue with streamlink, and the only thread I could find about said it was some sort of DDoS protection from youtube. I would assume it would also apply to videos if that was the case, but that's why I'm here and checking.

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
