iCloud Login Fails?

When I go to Settings / iCloud, my AppleID is there, but when I tap the disclosure triangle/icon (>), iOS asks me my to "Sign in with Apple ID" (i.e., enter password for my Apple ID).I enter the password but get the error message/alert:


Title: Verification Failed

Message: An unknown error occurred

Buttons: Cancel / Try Again


I tried updating my password at MyAppleID, to no effect.


I have 2-step verification enabled.

Addendum: I can successfully logout and login back again into "iTunes & AppStore".

Same here, only that I don't have 2-step verification.


Unfortunatly, it seems like iCloud based services don't work properly (Photos and Backup) because of that.

I have a similar problem, but the iCloud preference pane hangs forever and must be killed. When restarted it hangs again.


I was wondering if there was a way to sign out of iCloud using command line?

This is the iOS 9 beta forum - is the problem you're having an OS X 10.11 one?
