Need suggestions to Store and Retrieve Documents Remotely

Hello All,

I am trying to retrieve documents from  external server by using direct file location through Third party credentials. I found few smart services to get remote directory files.

1. Retrieve Files In Folder Over FTP

          I am little confused on server file path(Path to Folder, Destination Directory), I tried passing multiple combinations of file path but it didn’t work. The process is getting completed                  without returning any document. If anyone had already done this, kindly pass me the inputs.

    2. Get Remote Directory Contents  Over SFTP

        I tried using this smart service but its failing and the error as below.

       "Error Establishing SFTP connection. Confirm your hostname, username and password. Error Message: java.net.ConnectException: Connection timed out (Connection timed out)"

Kindly let me know if you have tried any of these smart services or if there is any other functions or smart services which we can use to remotely access files from Appian.

Kind Regards!!
