Overcast/RSS: "Publisher Server Error"

Podlove Publisher
1

Hey lovely people :slight_smile:

Problem
Overcast (iOS) shows all Episodes of my Feed but when trying to download it just shows “Publisher Server Error” (see screenshot).

These is the problematic (patreon) feeds:

What’s weird about it

  1. This problem only appears with Overcast and no other Podcasting App
  2. My “normal” Feeds (non-patreon) DO WORK in Overcast (https://gamedevpodcast.de/feed/aac/ + https://gamedevpodcast.de/feed/mp3/)
  3. When I diff both feeds, I only see the expected: different names/urls and of course itunes:block so that the Patreon feeds don’t appear in the search.

Does anyone have an idea what the problem could be ?

Sorry, can’t see any issues in these feeds, should work perfectly fine :man_shrugging:

Thanks for the reply! Interesting, I checked with another validator and there I saw this:

But I asked my provider and they said they support byte range.

Also interesting: The feed from our old podcast (https://textlastig.com/) stopped working on iOS as well and we didn’t change anything on it for a long time. It all happened in one of the last weeks. Very weird.

I’ll look into the byte-range issue. I feel like that has always been falsely reported but I haven’t looked at it in detail for a long time.

I looked into it but the implementation of the validator seems to be closed source. So I don’t know what they are checking but it is wrong. Here’s an example range request which works perfectly fine:

❯ curl -L https://textlastig.com/podlove/file/1218/s/download/tl254_nlp.mp3 -i -H "Range: bytes=0-127" --output -
