Hello,
the new 6.6 version features native nextcloud syncing without using WebDAV. This works on my Win10 machine but sadly not on Android. I've used the public adress for my nextcloud and the local address. I've tried to connect from the existing tresor and for a new one. The error is as follows:"No connection could be made to the provided Server. Please check your URL." I checked the URL, the public and the local one.
