I just updated my shared-hosted Nextcloud instance. Things are working, I also can reach my calendar, using the standard web interface. But all of my clients stopped syncing. These are DAVx-orchestrated Android devices as well as a Thunderbird calendar on Windows. All of them always expected the path https://<my.cloud.com>/remote.php/dav/calendars/<myusername>/<mycalname>/ and this should be still the correct path(?).
One thing:
When Iām using a browser and use this URL when logged-in in a parallel tab, I get:
This is the WebDAV interface. It can only be accessed by WebDAV clients such as the Nextcloud desktop sync client. (should be fine and shows, the instance knows something about the paths semantics).
If Iām logged out, things are different. After entering the same URL, Iām getting a login dialog but providing my credentials is failing silently and the dialog reappears, requesting another attempt.
