Issues listen or downloading certain podcast

I’ve had an issue with listening(streaming) or downloading certain podcasts. There is a specific show that I’ve subscribed too and listened to in the past, but about 3 months ago I suddenly couldn’t either listen to or download any of their episodes. It only seemed to be this one shows episodes that had issues. At first I thought it was because I was trying to stream it on mobile data, but even on a trusted wifi connection it wouldn’t work either. I’m at my wits end and would like to find out why this is happening. Anyone have any ideas??
