Can not connect to remote files using webdav in Writer

Since I have updated to LibreOffice 24.2.2.2 (Windows 10) I can not connect using the Webdav interface.
However, under Windows Explorere I did succeed to map a networkdrive using Webdav.
The moment I want to connect with LibreOffice Writer I can not connect to my remote files.
Also there is no diagnosis information visible, no error or whatsoever.

Anyone an idea or instruction?

regards,
André
