Libsyn not supported? ERROR: Unsupported URL

[redwrist]

I tried both the site and rss, youtube-dl http://yourmomshousepodcast.libsyn.com/ and youtube-dl http://yourmomshousepodcast.libsyn.com/rss. Getting "ERROR: Unsupported URL" on both.

Here's a log from a Libsyn site that reports "Unsupported URL":
