Kontact bug (?): Can't synchronize with CardDAV ressource

[Volker Wysk]

Hi

I've edited a contact in the addressbook, but I can't get the changes synchronized with my Nextcloud server (via CardDAV).

When I click on "Update addressbook folder" in the menu in the "Contacts" section of Kontact, then I get this message:

   Before syncing folder "Kontakte" it is necessary to have the resource online. Do you want to make it online?
   
I click on Yes, but then the dialog closes and nothing happens. Next time, the same question comes again. The changes don't make it to the CardDAV server, what can be seen in its web interface.


Any ideas?

Volker
