Sikuli4Net Unable to connect to remote server c#

Question

I need help, I followed all the steps correctly and examples but I did not find solution to this error. No connection could be made because the target machine actively refused them 127.0.0.1:8080.

• Firewall disabled
• vs 2010
• net 4.0
• SIKULI_HOME C:\sikuli

• Newtonsoft.Json -Version 6.0.4

      private void button1_Click(object sender, EventArgs e)
      {
          APILauncher launcher = new APILauncher();
          launcher.Start();
          Sikuli4Net.sikuli_REST.Screen s = new Sikuli4Net.sikuli_REST.Screen();
          Pattern ee = new Pattern(@"\img\a.png");
          s.Click(ee);
          //Start API Launcher
          launcher.Stop();
      }
