@Qazm Thanks for the info. I don't actually run the bridge that is used to make the podcast feeds available on the Fediverse. That is done by @dave.
The 50x errors may be what is causing some of the following failures some people have reported.
Currently the bridge (ap.podcastindex.org) doesn't have a web view and only shows the data. I don't know if there is a plan to show the data formatted page.
Hey @benjaminbellamy Does @Castopod use podping? An issue [1] was opened saying their feed wasn't being updated in the index.
When I looked it up, it has a priority of -1 which I thought meant it was a popding feed.
Since they don't release shows often, the ping may have been missed.
I requested a manual scan and it has been updated with the latest episode in the feed (8/2/2023). Before the update, the lasted feed in the index was 2/3/2023.
