Can you check what user agent is used to fetch the rss feed? We blocked empty user agents as well as names of different bots due to AI crawlers.

It fails for my reader as well, while slrpnk.net succeeds. I’m not sure what’s going on. RSS isn’t my bailiwick.

Edit to add: The W3C feed validator says it’s good, with some warnings 🤷
