error occurred during activation -iMessage on Mac

I am trying to use the iMessage function on my MacBook Air and it won't log in. The message "error occurred during activation" keeps coming up. It worked a few months ago, but after I updated my Mac it stopped working.

MacBook Air, macOS High Sierra (10.13.3)

"An error occurred during activation. Try again" When I try to log into my iMessage on my Macbook Pro, an error message pops up and reads, "Could not sign in. An error occurred during activation. Try again." This won't allow me to log into my iMessage, and it has been repeatedly popping up for about a week. Anybody know how to fix this issue?
