FaceTime & iMessage are not recognising my Apple ID?!

[Dr.MZafer]

After updating my Apple ID info. FaceTime & iMessage logged out of my Apple ID account on both my iPad and iPhone and are not logging back using the same Apple ID claiming that my user name or password was incorrect?! Surprisingly, it's logged in on both Messeges and Facetime on my Mac. My Apple ID is well and running on my iOS devices for the Appstore and all of my emails are verified with my Apple ID when checked online. I tried logging through a different account, which worked for that account but it didn't allow me back to my initial and primary account, I even tried to edit again some of the information on my Apple ID hoping that it'll allow me to sign in afterwards but with no luck, I tried both WIFI and cellular to connect and it also didn't work. Please help me! I need to sign my iPhone's and iPad's FaceTime and iMessage to my Apple ID again.
