There is some problem processing the url https://qurancentral.com/audio/mishary-rashid-alafasy/feed even though the url works for AntennaPod on Android. When I try to refresh the feed through kasts, this error pops up in the logs:
Error happened: Error::FeedUpdate "https://qurancentral.com/audio/mishary-rashid-alafasy/feed" "" 201 "Error transferring https://qurancentral.com/audio/mishary-rashid-alafasy/feed - server replied: "
If I try to curl that URL, I get a response that includes this:
<h2 data-translate="blocked_why_headline">Why have I been blocked?</h2>

So, my suspicion is that cloudflare is interfering. I’m not sure what AntennaPod is using as a library to access the internet, but it might have additional features to e.g. accept cookies to get around this(?).
Similarly, wget also seems to get around the cloudflare thing…
As for Kasts: it’s simply using the standard qt libs for network access. I’m not sure there is functionality in the lib that would allow to work around the cloudflare thing.
From quick testing it looks like this is simply happening depending on the User-Agent header.
curl -L -H "User-Agent: AntennaPod/1.0" https://qurancentral.com/audio/mishary-rashid-alafasy/feed
works while without the header it sends the cloudflare page.
Thanks JBB!
Kasts does send a non-empty user agent header, but it seems that it’s not accepted. Probably everything is blocked except strings in an allow-list. I have a suspicion that the AntennaPod user agent was probably added to some allow-list after users complained.
It’s probably a good idea to complain to the website admins about this issue.
