WebDAV upload issues since yesterday (11/16/2020) using Windows 10 RRS feed

  • Question

  • For the past year, we had successfully been able to use WebDAV and FTP to upload files from our on-prem Synology NAS to our offsite Synology FTP server directly thru Explorer.  But starting yesterday, uploading certain (older) files in this manner with WebDAV causes an error 0x80070021.  And, 0kb ghost copies appear on the FTP server which cannot be deleted.  This is a one-way error, as I can move files from the FTP to the NAS without issue.  If I unmap the WebDAV shortcut and reboot, I can use FTP just fine and delete the ghost copies without an issue, thru FTP protocol.  Local files are not affected by this issue, and can be copied to/from the FTP without issue.

    WebDAV allows me to work live in these files, while FTP does not.  How can I get the WebDAV protocol functioning properly again?
