I have some Nextcloud-accounts synced via CalDAV with DavX⁵. These accounts work fine and are still syncing.
However, when i want to connect a new account with DavX⁵, it shows the error message:
Couldn't find CalDAV or CardDAV service
It happens on different servers with different reverse proxy software and configuration (all nextcloud but different versions and different operators) and on multiple devices, that’s why i believe it might be a DavX⁵ issue.
