Need guidance on getting iMessage/Facetime working MacOS 10.13.1 New install

So I finally have pretty much everything working, except getting iMessage/Facetime to login.

I keep getting the message "An error occurred during activation. Try Again."

I have followed this guide: https://www.Tonymacx86/threads/how-to-fix-imessage.110471/#TOP2.2

haven't had any Success . Anyone might have a little more insight?
