Hallo zusammen


Ich habe einen Kalender auf Synology und einen auf einer Nextcloud. Ich synchronisiere diese Kalender mit meinem Handy (Samsumg S7) und mit zwei unterschieldichen Samsung-Tablets.
Einzig mit dem Handy meiner Frau geht der Sync nicht.
Handy: Samsung Galaxy S7, Android 8.0.0, CalDAV-Sync 0.4.32, Kalender App: aCalendar
Wenn ich einen Eintrag im Kalender erstelle und synchronisiere, dann wird der Termin nicht synchronisiert. Unter "Konte Synchronisieren" wird auch der letzte Zeitpunkt nicht aktualisiert.
Wenn ich danach in die Kontoeinstellungen gehe und die unterste Option (Synchronisieren beim Einschalten des...) aktiviere, dann wird der Sync sofort ausgeführt.
Jetzt kann ich im Kalender wieder Termine löschen und hinzufügen. Beim folgenden Synchronisieren passiert dann wieder nichts. Erst wenn ich die vorher gesetzte Option wieder deaktiviere, wird der Sync sofort ausgeführt.
Somit müsste man für jeden Sync die Option aus, rsp. wieder einschalten.
Auf allen anderen Geräten funktioniert das ohne diese Option.
CalDAV-Sync wurde bereits deinstalliert und neu installiert, leider ohne Erfolg.


Vielleicht kenn sich jemand damit aus?
Gruss
Markus


Wenn ich das Log aktiviere erhalte ich einen Connection Error:
