Podcast app not connecting on Mac OS Sonoma desktop

The app comes up, I can browse a little among shows. When I try to play one, I get an endless "loading" screen, though my computer is connected to the Internet, my Safari browser and email work just fine. I can go find those podcasts using the web browser, but Podcasts should work.

Anyone else experiencing this? Ideas? Workarounds?

Rebooting doesn't help. That much I know.
