The Messages
app wasn't longer able to send messages saying Not Delivered
, so I signed out. When signing back in I see this:
Note that Apple does see the login: I get an email saying so
The information in that email is correct, so then why the error message? Any ideas on this?

I used to have the same error on my device once.
In my case it helped resetting the NVRAM, which is one of the recommendations in Apple's documentation.
