my odyssey after upgrading to Owncloud 10 continues. I managed to get the Calendar and the Contacts working, also with the Android phone... but not with Mac OSX 10.12.
I configure the calendar per the documentation available and when the calendar tries to synchronize I get the following error:
The request for account “owncloud.rummels-acoustics.com” failed.
The server responded with
to operation CalDAVAccountRefreshQueueableOperation.
Does anyone know how to solve this?
