How do I fix error '0x80070057: CalDAV URL is empty.' when log in to iCloud?

When attempting to log into iCloud, I receive this message:

Error: 0x80070057: CalDAV URL is empty.

Every similar "thread is closed" without a resolve.

Is there a solve for this?

iCloud Drive browser access A couple days ago I started receiving an error (iCloud stopped responding) when trying to access iCloud Drive from browser, and it doesn't matter which browser I use, always the same. Of course I use "Send to Apple" and of course it's a total waste of time. Anyone having similar error who knows what to do?
