Nemo and Yandex.Disk. Access problems. Why?

Question

linux

Actually the problem
In Nemo I connect to Yandex.disk (YD) via webdav. For some reason I can't understand, I can create files on the POISON and delete them, but I can't copy, rename or move them. About trying to copy a file from one folder on the POI to another folder on the POI, I get an error - HTTP client error: Forbidden, when renaming - the same thing. Tried Nautilus. The same.
In MacOS everything works without problems. And it's not on the same computer. Mint is installed at work and at home - and both have such a problem.
Login and password from the user who has the rights to all these operations.
Tell me, please, what could be the problem?
