Kontake lassen sich seit Kurzem nicht mehr mit DAVdroid synchronisieren.

Seit Kurzem klappt die Synchronisierung der Kontakte vom Smartphone zu mailbox.org nicht mehr. Ich verwende DAVdroid. Die andere Richtung klappt wunderbar. DAVdroid meldet, dass "500 Internal Server Error" von mailbox.org zurückgegeben wird.

Hier der komplette Log (leicht anonymisiert :-)):
