### Region

Israel

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

When trying to download a stream from stripchat.com yt-dlp gives back "No active stream" even though a stream is live at the same time. If I paste the m3u8 of the same stream then yt-dlp works and downloads the stream.

sidenote:
I tried to set my yt-dlp to nightly but can't because I downloaded it from homebrew. and using yt-dlp --update-to nightly gives back:
"ERROR: You installed yt-dlp from a manual build or with a package manager; Use that to update"
and no documentation on how to exactly do that.

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below

Hints:
Looks like they're using .live as a host now
https://edge-hls.doppiocdn.com/hls/164812713/master/164812713_auto.m3u8 doesn't work but https://edge-hls.doppiocdn.live/hls/164812713/master/164812713_auto.m3u8 does so Stripchat extractor needs .live as a fallback I think. Also is there a way to also use xHamsterLive as it uses the exact same manifests but  doesn't work because of domain name.
