Receiver SFTP Channel giving error

Hi PI Experts,

My scenario is ECC->PI->SFTP server.

I am using Password based Authentication to send files to SFTP server using SFTP adapter.

Now SFTP adapter giving the error like "Message could not be forwarded to the JCA adapter. Reason: com.jcraft.jsch.JSchException: Auth failed".

I am able to login to SFTP server with provided User ID and Password through WinSCP tool. But when I tried to place files through SFTP adapter, it is throwing the above error.

I have configured the Server IP (not host name), Port and Server fingerprint.

I am using the PI7.31 SP08.

Could anyone please help me on this issue?

Thanks,

Govindu.
