Recently the plugin stopped receiving post updates. I tried raising the update time to 12 hours per feed but no luck.
Feed debug @ TTRSS returns:

I know, server side recently decided to restrict access to APIs and the webpages, you can see that here as well. Since the web clients probably also used those, all of them seem to be gone.

ATM, there is not much I can do about it other than giving a more informative error message.

[ALERTua]

it would be great if the error at least tells where to find more information.
