SUMMARY
Since re-installing a fresh Fedora 40 after using Fedora 39, I am no longer
able to add my nextcloud calendar or addressbooks in akonadi. The error message
shown in the window is completely useless (driver error, on German, couldn't
get it to show it in English), on the console it's a bit more usefull, 

org.kde.pim.akonadiserver: Handler exception when handling command
FetchCollections on connection akonadi_davgroupware_resource_0 (0x560355340ab0)
: Hierarchical RID does not specify an existing collection
org.kde.pim.davresource: Unable to fetch collections 320 "Ungültige Antwort des
Treibers"

STEPS TO REPRODUCE
1. Install Fedora 40 with akonadi 6.0.2
2.  Try to add a nextcloud ressource, either via the built in Nextcloud setting
in the drop down or by specifying the URLs manually

OBSERVED RESULT
You get the above error


EXPECTED RESULT
It works

The same nextcloud instance works with other software, e.g. a still running KDE
5.* based kontact on my desktop box, davx on Android etc.
