Windows officialy removed support for WebDAV. It still works, but nothing is guaranteed. It has stupid limitation on file size of 10MB, it can be lifted to 2GB (max signed 32 bit number) in Registry, but it is still not very much in modern world (I wanted to share my medial library via WebDAV and failed due to this limitation). It lose credentials on regular basis, errors are too vague («Wrong credentials» means both mistyped password AND expired server certificate), etc.
