What does "SSL protocol error" mean when connecting to an FTPS server?

Robo-FTP may report an "SSL protocol error" when it is unable to negotiate a secure connection with the remote server. This may happen when the server requires a client certificate for user authentication. The administrator of the remote server should be able to confirm if a certificate is required.

In Robo-FTP 3.8 and earlier this message was printed in the Trace Log, often with a reason code of 60000. In Robo-FTP 3.9 the "SSL protocol error" message also appears in the main console and Script Log.

Note: Some HTTPS servers also require client certificates for user authentication.
