sftp from iseries

i am trying to connect to a partner using sftp via the iseries. I am able to get to if using filezilla from a pc, but having issues when i try from iseries. I think it has something to do with the shared public key but not sure. Since i can connect via filezilla, is there a way of taking that key information off the pc import it into the iseries.

I ran sftp in debug mode and information is as follows:
