Mp3 of latest live stream (Patreon)

I need to download last nights live stream so I can convert it to mp3 and upload it to Patreon. But as you can see, YouTube is not letting me download it. It usually take a few hours before a live stream is available for download, but it's taking longer than usual. I've tried using several YouTube video downloaders, but they won't let me download it either.  Hopefully it allows me to download it by the end of the day.
