Q: Can no longer download episodes of my podcast

I can't check on the iOS Podcasts App, but otherwise everything seems normal. Today's episode has already appeared in the iTunes Store - which is pretty good going as it normally takes 1-2 days for new episodes to appear; you just got lucky. It plays from there, and when you subscribe to the feed in iTunes it downloads and plays perfectly well. 

CastFeedValidator validates the feed and confirms that the server will handle byte-range requests (as required by iPhones). However there is a redirect in place on Podbean (presumably for tracking purposes) - the given URL of this episode:

http://tweenerwrestlingpodcast.podbean.com/mf/feed/s5xzfs/OS16_-_Summerslam_2016 .mp3

redirects to

http://s70.podbean.com/pb/9fa47fa5b24ebcc8a8fb76cc8b4bb5b3/57cde89b/data3/fs160/ 969887/uploads/OS16_-_Summerslam_2016.mp3

This shouldn't cause any problems, but occasionally these redirects can do so. However you say it's been working up to now, so that wouldn't seem to be a problem.

So everything is normal as far as I am able to check. You should try it in the iTunes Store on a Mac or PC, and if you are having problems on an iPhone someone else here may be able to check it, or you could ask in the iPhone forum.
