Take a look at the reasons -

🍏Reason 4. An issue with the Apple Server
Lastly, the reason might be the Apple server. If nothing is wrong with your system and you are still facing the issue, Apple is at fault. Sometimes, Apple servers are down. So, you need to visit the System Status page of Apple and check.
