Caldav Sync isn't working

[ambergerit]

On OwnCloud 8.2.3 the Caldav Sync of Calendarplus 1.1.1 App isn't working

The Sync from iOS App to the Calender (creating new events) works. But The Sync (Download of online or on other iOS device created events) isn't working. The Main Calendar (not Shared ones) cannot be synced by Thunderbirds lightning.

In OwnCloud there is the Error Message:
