New Feed URL not updating

Question

I recently moved my clients podcast feed and set it up (with WP Podpress plugin) with the new feed URL. I submitted it to iTunes but it has yet to show an update:
Feed: http://calvaryqc.org/category/sermons/sunday-sermons/feed/
Podcast id: http://itunes.apple.com/us/podcast/calvary-church-quad-cities/id273511998

The feed validates, the source code shows all of the necessary header info for itunes - what am I missing... why isn't it updating?
Thanks for your help!

Answer 1

iTunes is looking for a feed at
https://www.calvaryqc.org/xml/podcasts/02080425.xml
and not finding it. The connection is a secure one - https - and when tested in FireFox reports that it uses an untrusted certificate: but even over-riding that shows that there is no file at that address. It is to that feed that you have to add the 'itunes:new-feed-url' tag (it's present on the feed you link to but simply links to the same feed so it's redundant).
Unless you can place a feed at the URL I quote above which iTunes can read (as it must have done once as there are episode showing in the Store, albeit rather out-of-date) you will not be able to redirect iTunes to your new feed.
