404 error response when connected to TrueNAS system

Hi all,

There is a connection possible to my fileserver via WebDAV, but no files or folders are shown. I get the 404 error from WinSCP.
I have added the logs of WinSCP.
It seems like there is some sort of authentication problem.
Can someone help me?

Would this help?
How to connect to a server that does not allow an access to the root path?

This was the solution, thanks.
I pointed to the shared directory in Advanced Site settings in WinSCP.
