[Bug] Cannot subscribe Debian news RSS

[TranslucentFoxHuman]

Describe the bug
We cannot subscribe Debian news RSS (https://www.debian.org/News/news).
When I try to add that RSS feed, the app displays “Processing feed error,” and I cannot add the feed.

I have confirmed that when I access the URL, the RSS feed XML downloads, and that the feed can be subscribed to in other RSS readers.

To Reproduce
Steps to reproduce the behavior:

1. Open 'https://www.debian.org/News/' in your favorite Web browser.
2. Long‑press the 'RSS' button in the upper‑right corner, or right‑click and copy the URL. It should become 'https://www.debian.org/News/news'.
3. Open Readrops, goto 'Feeds' tab, and tap '+' button in the bottom-right corner.
4. Paste the copied URL into the input field labeled “Enter an URL.”
5. Tap 'Validate' button.
6. Readrops displays “Processing feed error,” and I cannot add the feed.

Expected behavior
The feed should be added successfully without any errors.
