Weird iCloud Authentication Errors

I keep having an issue with iCloud on my MacBook Pro (Early 2015 model, up to date software) where even though my credentials are all correct, the system re-prompts me for my credentials routinely and then rejects them, even though the ID and password are correct. It doesn't say why it rejects them. It just says "an authentication error occurred." My only resort is to reset my ID, which of course is a serious pain with Apple. It's also happening with my Google account in the "internet accounts" tab in settings. Again, username and password are correct, it just tells me an error occurred, inexplicably.

Are you running any anti - virus programs? Using a VPN?

Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.
