Anyone know what's going wrong

Downloaded youtube-dl from AUR and now getting

me@manjaro [2]> mpv acestream://10a85cd65dc8ba3eefa31d6ffef640e44d21e50d [mpv_acestream] AceStream protocol detected. [ffmpeg] http: HTTP error 500 Internal Server Error Failed to open http://127.0.0.1:6878/ace/getstream?id=10a85cd65dc8ba3eefa31d6ffef640e44d21e50d.

Make sure you are using the latest version; see https://yt-dl.org/update on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.

With a different channel, getting
me@manjaro [124]> mpv acestream://a30c60fe37ef98a276b0daafcdc0527f534142c5 [mpv_acestream] AceStream protocol detected. _(long delay)_ Failed to open http://127.0.0.1:6878/ace/getstream?id=a30c60fe37ef98a276b0daafcdc0527f534142c5.
I think the difference is in the broadcasting of the channel, with the latter not broadcasting
