WebDAV write file

Hello,

I have an advancedsettings.xml (and an inofficial plugin) which uses webdav locations
webDAV (wiki)

In all cases, read and modify existing files and directories works fine.
But Kodi is not able to create new files or directories. The WebDAV user has permission to do so.

Here are some lines from my logfile:
16:39:11 T:4880 ERROR: CCurlFile::Open failed with code 404 for davs://USERNAME:PASSWORD@HOST/FOLDER/
16:39:11 T:4880 ERROR: XFILE::CDAVDirectory::GetDirectory – Unable to get dav directory (davs://USERNAME:PASSWORD@HOST/FOLDER/)
16:39:11 T:4880 ERROR: XFILE::CDirectory::GetDirectory – Error getting davs://USERNAME:PASSWORD@HOST/FOLDER/
16:39:12 T:4880 ERROR: XFILE::CDAVDirectory::Remove – Unable to delete dav directory (davs://USERNAME:PASSWORD@HOST/FOLDER/) – 404

16:39:13 T:4880 ERROR: XFILE::CFile::Copy – Failed write to file davs://USERNAME:PASSWORD@HOST/FOLDER/settings.xml
16:39:13 T:4880 ERROR: CDAVFile::Delete – Unable to delete dav resource (davs://USERNAME:PASSWORD@HOST/FOLDER/settings.xml)

I tested this behaviour on several OS, like Windows 10 and Raspbian.

I don’t know, if this is a bug or if there is any solution to that. I searched but found nothing.
