What exactly is your question/problem? Are you asking why the transfer fails? Is it always the same file? "set times: Operation not permitted" happens, when scp tries to update the file timestamp and you are not an owner of the file.

Upgraded to latest version today. Tried to sync from my Win10 local to an HDD attached to my RPi running Volumio. I've attached a screenshot of the error as well as the session log. It seems that once the error message posts, the file transfer continues, I think on the file causing the error. Not sure. But the transfer rate is at a snail's pace.

Thanks in advance.
