Published podcasts can not be opened

I connected my podcasts (which are on Podbean) via apple podcast connect and in my account they appear as published. But when I follow the URL, it opens the app saying "Can't connect right now". It's been more than 3 says like this now, so it doesn't seem to be a question of update. Also, I find all kinds of other podcasts, so it isn't my internet connection either. Could anyone perhaps help me to find out what the issue might be? Thank you!
