John, I think IBM no longer recommends port 990, see II13516. Also, most of our grief with ftps came from firewall issues. "Connection refused" was a common error when the z/OS firewall was not allowing that incoming traffic. We favor ssh over ftps. Is your Bluezone client internal to your network?
Hope that helps...
