“Problem Reaching your podcast feed”

Hi, I have installed the plug-in and love that there is both widget and page shortcode. I’d love to use it however when I enter my podcast feed url it says it’s not valid. I’m not sure what’s wrong with it as we are going out to itunes, Gplay, stitcher, and others with the feed.

Here is the error:
There was a problem reaching your podcast feed. (Feed: https://www.taconightaudio.com/adulting-misadventures?format=rss)

any help would be appreciated. Let me know if you need any other information. Thanks!
