facetime and imessage aren’t working

https://support.apple.com/en-us/HT201422

I am on Mac Book Air. MacOS 10.13.6 I have verified my iCloud account repeatedly.  Each time I try FaceTime or iMessage I get the same reply.

"An error occurred during activation. Try again." (again, I have verified my iCloud credentials repeatedly)

I have followed EVERY suggested step I found online for fixing this problem.

I have been receiving this activation error for about 4 days after verifying my iCloud account and linking my MacBook Air to iCloud in System Preferences -> iCloud -> Account Details -> Devices

I have both my iCloud account and other than iCloud account as my contacts in my iCloud setup

I have 2 factor authentication setup with my mobile phone.

My date and location are correct and verified.

My personal info is setup correctly in iCloud setup (on my Macbook)

I had to login to iCloud to post this reply, so that's a "no-brainer"

Let me know if you need more technical details.

Malware Bytes (Free On-Demand version only )

Free version of CleanMyMac 3

I have the Mac Book's native VPN client configured to connect to work, but I rarely use it. It's never connected when I try to use imessage or Facetime

Clock is accurate to the second

Are you able to login to say iCloud?

Any luck yet?

I do not have any other Apple devices (forgot to mention that)

Are you running any Anti-Virus or Cleaning Apps?

Are you using a VPN?

Is you Clock within seconds of the right time?

Remove CleanMyMac 3 per their directions then make sure it didn't leave any files using etrecheck.

Restart

I'll try that asap. Thnx for your time.

Did this solve the issue for you? I am having the same problem?

We often never hear back one way or another. :(
