Winscp cmd line with private key failed - Server refused our key

Hi All,

I am able to login into a SFTP server manually with a private via WinSCP 5.7.2 but failed to connect via script.
Below details for reference:
>winscp /script=script.txt /log=C:\Temp\sftp.log
option batch off
option confirm off
open sftp://NEUSER:N3020@3.125.64.21 -privatekey=D:\\key.ppk -Passphrase=N3020
cd /sftp-boubyan
put "C:\Temp\file.zip.gpg"
# Disconnect
close
exit

Please attach a complete session log files both from GUI and script using the latest version of WinSCP.
