SFTP fails on copy to server where wrong case but right directory

[andrewheard]

using Windows FFS 11.4 on source
Raspberry Pi Linux on destination
demo SFTP source C:\test\
demo SFTP destination sftp://volumio@192.168.20.19:22/test|zlib|pass64=dm9sdW1pbw==

if there is a destination directory sftp://volumio@192.168.20.19:22/test/MIXED case/
BUT I copy from source folder C:/test/mixed case/
compare (F5) works OK
but an error msgbox is displayed after a delay when sync (F9) is attempted, msgbox text:
----------------------
Cannot move file
"sftp://192.168.20.19/test/MIXED case" to
"sftp://192.168.20.19/test/MIXED case".

LIBSSH2_ERROR_SFTP_PROTOCOL: SFTP Protocol Error - LIBSSH2_FX_FAILURE [libssh2_sftp_rename]
----------------------
If I manually correct the case of the Windows folder name and/or Linux directory name, the sync works correctly. Happy new year.

Did you copy and paste the error message? "Cannot move [...] MIXED case to [...] MIXED case" doesn't make sense.

Are you able to reproduce the error?

I assume your base directory pair is

sftp://volumio@192.168.20.19:22/test
C:/test

Hi Zenju. Thanks for your reply. I edited the directory names in my report because the actual directory pairs had more personal information in them. So the msgbox is not an exact literal copy/ paste, however the intent and character case is the same. I'm sure I could reproduce the error if needed.

"Cannot move [...] MIXED case to [...] MIXED case" doesn't make sense. - well that was the msgbox text!

I'm sure I could reproduce the error if needed.

Can you list the steps that got you to this peculiar error message? Also a few screenshots would be helpful.

I started a simple test scenario from scratch with 2 folder names with same case, then renamed either side, but after many attempts I couldn't reproduce the error. I certainly didn't imagine the error but unsure how to reproduce it now sorry. Thanks for your interest.
