Issue Logging in to iMessage after updating to Catalina

Hey All,

I have a Late 2015 MBP that I just completed an update to Catalina (version 10.15.6). I cannot get iMessage to accept my Apple ID. I know I have the correct login because I tried to login to my account via web and it worked, and I am posting here.

It will either say an error occurred or the following:

"Could not sign in to iMessage.

The user name or password was incorrect. Try again."

MacBook Pro Retina

Can be related to a server side error-

  1. Reset SMC by following the directions applicable to your MacBook here ➔ How to Reset SMC. If that does not solve things then-
  2. Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM.  If that does not resolve things then-
  3. Try signing on to iMessage after a few hours if this happens to be a server side issue.
