Error Message: Not a valid PFX data

Error Message: Not a valid PFX data

Action:
When trying to use a public or private key for authentication with FTPS connection manager and when testing the connection or when running the package I get the following error message:

Error Message:
Not a valid PFX data 

Solution:
             
            You see this error message because the FTPS connection manager doesn't support authentication with a public or private key. You should use SSH connection manager instead.
