Solutions of the Error Occurred During Activation

Method-2: Check Your Apple ID

Check to see the Apple ID and also the password are both accurate. Is your Apple ID a valid email account or just a username and password combination? Regarding FaceTime to work here on touch Bar, you must have an Apple ID which is configured as such an e-mail address. Sometimes when your ID is only a simple username (i.e., it does not contain a @ sign), you will have to either modify this to an email or otherwise just use a new Apple ID using FaceTime.

Verification of all usernames email accounts must always be completed by visiting the Apple ID website. Whenever your Apple ID also isn’t associated with an email account, you should alter it over there.

After you have completed the DNS updates, turn off the power and restart your tablet or Macbook. Now check FaceTime once more.

Do you suspect that your FaceTime, as well as iMessage accounts, have been blocked or throttled? 

Occasionally, the cause for iMessage but also FaceTime being inaccessible is because of a backside delay or blocking on the server.
