I can connect to a SFTP server (Linux) at my workplace from a Windows Server 2012 machine via PSFTP, sftp.exe and another staff showed a connection via scp from a command line.
But despite using the same private key, converted from Openssh via PuTTYgen, I cannot connect with WinSCP. It keeps saying server refused the key and then asks for a password. But I did not configure a passphrase for the key and the user account is not using password. Not really sure what I am doing wrong or where to begin troubleshooting.
If anyone has any thoughts, it would be greatly appreciated.
