• Additional info (logs errors etc)
  No error logs related have shown.
  I have tried it on the official rsshub.app, it wasn't the problem.
  There is a workaround, shutdown rsshub and Redis, delete the Redis cache, and reboot everything, then the feed will update the newest feed once. But you have to keep doing this workaround to keep fetching the newest feed

Actually, after I deleted the Redis cache last time. The update bug is gone. Not sure why but I am closing the issue for now.
I will keep monitoring this issue and reopen this issue if the bug appears again

Confirmed that deleting the Redis cache doesn't totally eliminate the issue.
I have updated the involved route at the top of this issue page

I found the same issue, after some test, looks like facebook will return a login page without any content after a few request, below is the $.text() for the returned request

Log into Facebook | FacebookFacebookYou must log in first.Phone number or emailPasswordor<input type="hidden" name="_fb_noscript" value="true" />Forgot Password?

the router cannot parse anything out of this, maybe need to implement rate limiting to prevent facebook from knowing we are crawling their site?
