I read a Belgian newspaper named www.lesoir.be
While some of their feeds work well, some others return this:
2025-07-23 06:29:24: Not an RSS feed (553)
2025-07-19 21:55:03: HTTP Error (403)
Example of a working feed: https://www.lesoir.be/rss2/9/cible_principale
Example of a failing feed: https://www.lesoir.be/rss/31892/cible_principale
I see the path being slightly different, but I assume it’s a feed level that something is off.
Can you please help me understand the difference between the 2 feeds? Is it something that I can fix on my side, or that I should report to the newspaper?
Thank you!
