copy local machine from remote machine shared folders can'work

Bug Description

We have a RustDesk Server Pro 1.4.6 running in docker.
Our problem:
I connect to a machine (win10-11) that has multiple shares, I can copy/move files from my own machine to these shared folders without any problems.
However, if I want to copy anything from these shares to my own machine, it doesn't work, the download doesn't even start.
However, it doesn't work in the file transfer window either.
However, if I copy from the C: drive of the remote machine to my own machine, it works fine.

I read the forums and found the same problem, but I couldn't find a solution.

We reviewed the rustdeskserver settings, firewall rules, ports, and we also reviewed the installer generated with the server. We didn't find any problems anywhere.

I would like to ask for your help in solving this problem.

How to Reproduce

TI tested it in several ways.
I checked the settings.
I suspected the ports at first.
But I found everything fine.

Expected Behavior

It would be nice if it worked to copy from shared folders to your own computer via the file transfer window.
Maybe drag&drop could work, like in teamviewer.
