iCloud login on iPhone 11 fails for “unknown error”

Something’s wrong with iCloud on my iPhone 11 (iOS 27.0.1): it suddenly asked me to input my iCloud account’s password, but whenever I do it kept saying “An unknown error showed up” and wouldn’t log me back in and now it says “Impossible to communicate with server”. I checked Apple Status, but the service seems to be up….so why can’t I log in to my iCloud anymore?

Yeah, my issue is showing in the system status - it wasn’t before, that’s why I posted.
