SSL Error: The token supplied to the function is invalid

  • One possibility is that you are trying to connect to the server with Implicit SSL, when the server requires an Explicit SSL connection. On the Address field, to the left hand side, next to the word "Address" you will see a icon with a drop down arrow, select "FTP Over SSL (Explicit)" from the drop down menu.
  • You may need to create a self signec client certificate. Go to the Favorite properties: 
    Select the Tools tab, click on Favorite Properties.
    Go to the Connection - TLS dialog
    Click on Create Cert 
  • This can also occur when connecting to an incorrect port, or the server just does not support SSL.
