com.mks.api.response.APIConnectionException: Remote host closed connection during handshake

Hi,

I keep getting this error when running my code:

com.mks.api.response.APIConnectionException: Remote host closed connection during handshake

import com.mks.api.CmdRunner;import com.mks.api.Command;import com.mks.api.IntegrationPoint;import com.mks.api.IntegrationPointFactory;import com.mks.api.Option;import com.mks.api.Session;import com.mks.api.response.APIException;import com.mks.api.response.Response;publicclass MksMain {          @SuppressWarnings("deprecation")          publicstaticvoid main(String[] args) {                    String host = "";                    int port = 7001;                    boolean secure = true;                    String user = "";                    String password = "";                      try{                    IntegrationPoint ipf = IntegrationPointFactory.getInstance().createIntegrationPoint(host, port, secure, 4, 11);                    Session session = ipf.createSession(user, password);                     CmdRunner cmd = session.createCmdRunner();                      cmd.setDefaultHostname(host);                    cmd.setDefaultPort(port);                    cmd.setDefaultHostname(user);                    cmd.setDefaultPassword(password);                      Command connect = new Command(Command.SI, "connect");                    connect.addOption(new Option("",""));                      Command checkout = new Command(Command.SI, "co");                    checkout.addOption(new Option("", ""));                      Command disconnect = new Command(Command.SI, "disconnect");                    connect.addOption(new Option("",""));                                          cmd.execute(checkout);                                   Response response = cmd.execute(checkout);                                       String resID = response.getResult().getMessage();                     System.out.println("Established connection " + resID);                    }                    catch (APIException e){                              System.out.println("oops");                              e.printStackTrace();                    }              }}

Happens after line cmd.execute(checkout);

Any ideas?

Thanks in advance!
