Utilizing the FTP node in IPA: SFTP Connection in the Cloud

We are having a difficult time using the FTP node to establish an SFTP connection in the Cloud. We created a configuration in the Process Server Administrator that contains the UN/PW and site info. When clicking on Test, we get a successful message back. These same credentials resolve successfully using any SFTP Client (WinSCP, FileZilla, UltraEdit, etc). However, when trying to run the flow on the server, it consistently fails. Do we have to generate the ssh keys for us to utilize this? If so, how do you get those keys to the cloud? Thanks!
