Among other things, in the above document, see Check Apple’s System Status page. You can check there to see if the needed server is available when you need to use one.

Also, below are the alert messages given in the document. But, receiving others is a possibility.

Use the steps above if you see one of these error messages:

What to do when the Mac App Store shows a different Apple ID for software updates https://www.macworld.com/article/3267709/mac-app-store-apple-id.html. This document refers to a prior owner, but is also applies to cases where a current owner's old Apple ID is the problem.

Basically, If an app is purchased/downloaded using one Apple ID, then you can't update it with another Apple ID. The app is inextricably linked to the first Apple ID. You'll have to delete it and repurchase/download it again with the second Apple ID. 

What happens when you try? Error message(s)? Account disabled? More information would help.
