"Feed not found" for every GitHub feed

[F1248]

NetNewsWire no longer retrieves new articles from my existing GitHub feeds, although no error message is displayed. The last retrieved articles are from 8 January 2024 noon UTC.

When I try to add a new GitHub feed (e.g. https://github.com/Ranchero-Software/NetNewsWire/commits/main.atom) to either On My Mac or iCloud, I get this error message:

Feed not found
Can’t add a feed because no feed was found.

According to The W3C Markup Validation Service, these feeds are valid.
This is possibly related to #4181.
It makes no difference whether I enter the URL directly in NNW or in Safari.
GitHub's blog is not affected.

This occurs on both devices with NetNewsWire Version 6.1.4 (6120):

• MacBook Air M1, macOS Sonoma 14.2.1
• iPhone 7, iOS 15.8

Looks like a GitHub bug — it’s not returning feed data for that URL.

Many thanks for the quick reply!
Then why are the feeds valid according to The W3C Markup Validation Service?
(I accidentally posted an invalid link to this before.)

it’s not returning feed data for that URL.

However, curl can transfer data from these URLs and online RSS readers such as RSS Viewer can parse these feeds.
curl https://github.com/Ranchero-Software/NetNewsWire/commits/main.atom

How can I get more detailed logs about the error?

When I run curl https://github.com/Ranchero-Software/NetNewsWire/commits/main.atom I get some JSON — but not a valid feed of any kind. What do you get?

Same here for https://github.com/chromium/chromium/commits/main/base.atom

Fix seems pretty straightforward - NNW should pass "Accept: application/atom+xml" for requests.

As a temp workaround I use https://docs.rsshub.app/routes/programming#github

GitHub fixed it!
