Calendar 400 icloud error

I'm getting this error when Calendar is trying to access iCloud calendar. I've followed all the steps suggested such as logout, reboot, uncheck and check various accounts, disable and enable icloud. Nothing help.


The request for account “iCloud” failed.



The server responded with

After trying most if not all of the solutions on the suggested page (including deleting and reloading the calendars from archives) it's still coming up. Is there any other option for fixing? The error is incredibly annoying.
