Error adding new podcast: "Unable to verify the validity of this URL"

[cag8f]

Hello.  I'm trying to add a new podcast using the URL https://soundcloud.com/armorypodcast, but MusicBee returns an error, "Unable to verify the validity of this URL" (screenshot).  How can I resolve this?  I encounter the same error if I use the podcast's iTunes link (https://itunes.apple.com/us/podcast/the-armory-podcast/id725209377).

Thanks in advance.

I am having the same error as the user above.

Here is the RSS link for the podcast I'm trying to add:

https://kboo.fm/program/film-show/podcast

And here is the iTunes page (could not find the show in MusicBee's iTunes podcast directory search either):
