Describe the bug

Hi, I encountered a persistent issue with self-hosted RSS feeds in Folo.

Description

I deployed an RSS service using we-mp-rss (for parsing WeChat public accounts) and exposed it through a public URL.
The feed is hosted on a private cloud server and is automatically updated daily.

During the first and second days, Folo correctly detected and loaded the updated content.
However, starting from the third day, Folo stopped updating the feed — even though the RSS source itself continued to refresh daily.

For example:
If I subscribed to the feed on October 7, Folo automatically updated on October 7 and October 8,
but from October 9 onward, no new content appeared, even though the feed itself had changed.

If I unsubscribe and then re-add the same RSS link, Folo immediately recognizes and displays the latest entries again.

Evidence

1. The RSS feed has already updated content

2. Folo remains stuck at October 8
   (Note: In a previous test, it stayed stuck at September 25. When I reloaded the subscription on October 7, it started updating properly for October 7–8 again.)

3. After unsubscribing and re-adding the feed, Folo correctly loads the new content

---

I’ve tried several approaches, including rebuilding the self-hosted RSS service,
but the problem persists — Folo always stops updating automatically after about two days.

Could you please look into this issue? It would greatly improve the experience for users relying on self-hosted RSS feeds.
Thank you for your time and your great work on Folo!

No files, tests, or entry points are named. Reproduce the issue with the described self-hosted we-mp-rss feed and compare feed updates before and after the two-day point. Done means the existing subscription continues displaying newly published entries without being removed and re-added.
