can't sign in to icloud from my macbook pro

I can't access my icloud account from the "Preferences" window. I can access inside the appstore and online as well.

But I can't use contacts, notes, reminders, etc on my laptop because Apple says: "you can't sign in right now, try signing

in later".

I already revised several options including deleting keychains related to icloud and the only option that does work is

by creating a new user but this is not an option for me since I would have to change all my user details.

Anybody knows a solution to log in to icloud without having to sacrifice changing my current user settings?
