moving out of squarespace to powerpress on WP

Your show’s Squarespace-generated podcast feed URL is:
https://jenniferholtslander.com/faith-at-home-podcast?format=rss

To import it into PowerPress, follow these steps:
1.) Log in to your WordPress site
2.) Install and activate the free PowerPress plugin
3.) Go to PowerPress >> Import Podcast
4.) Click the Podcast from Squarespace link
5.) Copy the feed URL above into the Podcast Feed URL field; leave the Default podcast feed option selected unless you’re planning on using a different type of feed; check the import program information and import iTunes artwork boxes and click the Import Podcast button at the bottom of the page

Note that this process imports your episode Posts/notes only, it doesn’t move your podcast media files to a different location unless you’re also planning on using Blubrry Media Hosting. In which case, you should also check the Migrate media to your Blubrry hosting account box.

When I do that I get this error and nothing proceeds. I have no idea what to do now!

cURL error 51: SSL: no alternative certificate subject name matches target host name ‘www.jenniferholtslander.com’

Are you giving PowerPress the full podcast RSS feed URL?:
https://www.jenniferholtslander.com/faith-at-home-podcast?format=rss

Just did it again to be sure I was. Here are the same results.

This is a plain text copy of the podcast feed’s XML:
https://media.blubrry.com/webm/ins.blubrry.com/webm/faith-at-home-podcast.xml

Download that file to a local drive. Go thru the steps described here:

Except for step 5. Instead of using the Squarespace feed URL, click the Browse button and select the XML file you downloaded to your local drive and complete the import process.
