Could not sign in to iMessage. Error message.

Could not sign in to iMessage.

An error occurred during activation. Try again.

All of my device cannot sign into messages/iMessage. Only my iPhone is sending/receiving messages.

I've tried shutting down messages on all my devices; simultaneously powering down all devices, and signing back into iMessage. No effect.

Can anyone help me understand how to get messages working across my Apple products (iPad, MacMini, iMac, MacBook).

I did a Command-Option-P-R to reset PRAM and fixed problem on Macbook. I would get error on iMessage login or authentication failed message. All good now.
