Hello,
Having this error since 2017, opened new apple id on same number. IMessage and FaceTime work on phone number but not with apple id on iPhone, but on mac i can not log in and constantly seeing message An error occurred during authentication.
Tried every solution I found on internet, but no help.
Is there a way that problem is in phone number that was used on previous apple id?
Please Help

Have someone else attempt to sign in using their Apple ID. If they can successfully sign in and use Messages/FaceTime, it may be your Apple ID. Someone I know had this happen and I was able to sign in using my Apple ID. After a call to Apple Support and then being elevated to a tier 2 support person, it turned out it was a problem with their Apple ID. It took the software engineers 3-4 days to fix the problem. When calling Apple, make sure you tell them it is an Apple ID problem so you don't get charged.
You can also try signing in on another device/computer. There have been a couple of posts where people's device/computer was blocked. You will need to contact Apple for that problem also.
There is a contact link.
