WebDAV why no write permissions?

Question

linux

There is a debian server on which I installed WebDAV via Docker.
I had to install WebDAV the way I want to, just mount a network drive on Windows 10 and work as a local drive, via the Internet via http.
There is a strange problem, when connecting through the free CyberDuck program, the connection occurs and I have write and read rights, but if I connect the disk through standard windows 10 tools, then there is reading, but there are no rights to write, the same problem on MAC through Regular connection via finder is not possible to write files.
How much? Any thoughts?
