COPSSH User Login Problem (bad owner or chroot)

Hi There,

I have Copssh running on Window Server 2012 R2 version 6.3(build 9600). I've tried to use Copssh 5.1.1_x64 on 2012 R2, but I receive the following error:

" fatal: bad ownershop or modes for chroot directory compnent "/" "

" Accepted publickey for username from xxx.xxx.xxx.xxx port 50199 ssh2: RSA SHA256:CgwNx..................................."

This is the result for "sftp -v -i "PrivateKey" username@xxx.xxx.xxx.xxx"
