WEBDAV and FTPS funktionieren nicht

[BertMod]

Hi support team, I'm using Keepass2Android on my phone (Samsung S10; Version 1.10-pre) and tablet (Samsung TabA9+; Version 1.10-pre). Both have Android 12.
My keepass databases are on a new Fritzbox 7590 ( FRITZ! OS: 7.59) stored on FritzNas (certificate from letsencrypt.org).Access via WEBDAV does not work; the error "File not found" appears. With access via FTP (not FTPS) I can open the files.
What can I do?

Hello, here is some important additional information about access via WEBDAV.
