FTPS File Transfer Prerequisites

Hello All,

 We have a requirement to send document to another system using FTPS.

  Ive installed the required plugin.

  I have added third party credentials in admin console.

  When I execute the process to test the connection, I get the following error message:

There was an error opening the connection to <servername>. Received fatal alert: handshake_failure

Is there anything I miss here?

Also, please note this is on premise environment. Should we need to set up FTPS server exclusively for Appian to send files?
