Describe the bug
I tried to import my contacts.vcf into the contact tab of my NextCloud. Many contacts went well but on some just failed (screenshot). Browser console log: "/remote.php/dav/addressbooks/users/XXX/kontakte/403968CF-0E25-4D92-8511-A39642C2F1F8.vcf?photo:1 Failed to load resource: the server responded with a status of 404 ()" This Error all along.
I use this https://www.qnapclub.eu/en/qpkg/348 repo on my QNAP TS X53. Everything works well with my Nextcloud, so I think the compatibility should be fine.
