Hi,
I have tried pretty much everything i could find on the internet to log in to Imessage but I still get an authentification error message. I have used this website https://www.hawkdive.com/imessage-activation-error-occured-mac/
Is there anything that you would know could work?
Many thanks,
MacBook Air 13", macOS 10.13
Some things to try if you haven't already tried them.
Messages - If you can‘t sign in to your iMessage account or FaceTime on your Mac.
Are you running any anti - virus programs? Using a VPN?
Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor. Please use copy and paste as screen shots can be hard to read. Click “Share Report” button in the toolbar, select “Copy to Clipboard” and then paste into a reply. This will show what is running on your computer. No personal information is shown. If the log won’t post, try posting it in Pastebin and provide a link in a reply. After pasting the report in a PasteBin page, go to the top of the page, and copy the address in the URL bar. Paste that in a new reply. Pastebin.

I have this problem too, on my Mohave MBP, but not on my Catalina MBA. See If you get an error when trying to activate iMessage or FaceTime https://support.apple.com/en-us/HT201422 I am not sure is anyone is getting this problem fixed at this time.
