icloud Calendar sync gives a 403 error

Hi,


I just updated El Capitan latest beta to Golden Master... But now I have added a new Calendar subscription and I get the following error:


Toegang tot account 'iCloud' is niet toegestaan.


De server reageerde met:
'403'
op de bewerking 'CalDAVAddSubscriptionCalendarQueueableOperation'.


English translation:

Access to account 'iCloud' is prohibited.


The server reacted with:
'403'
on the operation 'CalDAVAddSubscriptionCalendarQueueableOperation'.


Is this a bug? What should I do?
