[App_rpt-users] WinSCP root login

I have added a password for root login, and in sshd_config changed to PermitRootLogin yes. I can login as root locally with the correct password, but WinSCP says ' access denied '. The auth.log shows: sshd[1643]: Pam_Unix(sshd:auth): authentication failure; logname= uid=0 euid=0 TTY=ssh ruser= rhost=192.168.39.121 user=root Len WB2HKK
