iCloud authentication issues

1) When signing into iMessage, I get an authentication error "an error occured during activation"


2) When attempting to set "unlock Mac with Watch" I get "Your Mac must be signed onto iCloud..you can sign in using iCloud preferences..."


but I am signed in, all the other iCloud stuff works - .i.e iCloud drive, photos, etc...

I have tried signing out and back in -- but still am stymied.



Any suggestions?

These problems with iCloud authentication persist in Beta 4.


1) Messages will not authenticate Apple ID -- " Could not sign in to iMessage. An error ocurred during activation..."


2) FaceTime - "this account has no reachable addresses. Please sign in to Appleid.apple.com in order to add one" (I AM signed in and there are addresses at Appleid.apple.com and all my iCloud things like photos, app store, etc. work)


3) Unlock With Watch - "you must be signed into iCloud..."


Any clues?
