SFTP Receiver Error

Hi all,

I'm trying to configure an IDOC to SFTP scenario. Has anyone tried using Advantco PGP SFTP adapter before? I'm getting an error in my communication channel. I have already configured all the module parameters. Also, all the Connection details are correct. But I'm still getting this error in the comm channel monitoring in RWB:

Unable to forward message to JCA adapter. Reason: java.lang.Exception: Cannot connect to SFTP server.

The public IP address is already allowed in the SFTP server. Should the private IP address also be allowed? Or what else can be missing in the config? Are there steps needed to be performed by the Basis besides the netweaver key storage?

Thanks.

Regards,
