Cannot create an vault via WebDAV in mailbox.org-drive, neither from desktop(linux) nor from Android

Hello,

I cannot create an vault via WebDAV in my mailbox.org-drive neither from desktop nor from Android.

A) Desktop:
I use cryptomator version 1.14.0 (flatpak-1) on linux mint 22.0 (kernel 6.8.0-45).
The mailbox-drive is mounted in home/user/mborg.
After password creation I always get an error:

Error Code 91OE:CFA7:CFA7
java.nio.file.FileSystemException: /home/user/mborg/as: Das Argument ist ungültig

B) Android:

Device Info

Cryptomator v1.10.3 (2939) F-Droid
Android 14 / API34
Device Pixel 4a

Unfortunately, same problem. After creation of the password I can see a message: Authentification failed.
The creation of the WebDAV connection to mailbox.org (https://dav.mailbox.org/servlet/webdav.infostore/) is successful.

I have no ideas about the reason and how I can create an vault in the drive.
I am thankful for all help and information.

Hello,

yesterday I tried to create vaults on the top level - the level which is shown after entering the vault name.
This is not possible.
Vaults can only be created in the folder “public infostore” or in the subfolder of “Userstore”.
