I'm using Smartfoxserver api on Unity3d, it was working fine before I recovery my macbook, but now gives a connection error as below :

Http error creating http connection: System.Net.Sockets.SocketException: Connection refused

  at System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP, Boolean requireSocketPolicy) [0x00000] in <filename unknown>:0

UnityEngine.Debug:Log(Object)

SFS2X_Connect:OnConnection(BaseEvent) (at Assets/SFS2X_Connect.cs:2758)

Sfs2X.Core.EventDispatcher:DispatchEvent(BaseEvent)

Sfs2X.SmartFox:ProcessEvents()

SFS2X_Connect:Update() (at Assets/SFS2X_Connect.cs:2764)

here is connection code:

using UnityEngine;

using UnityEngine.Networking;

using UnityEngine.UI;

using System.Collections;

using Sfs2X;

using Sfs2X.Core;



    public class SFS2X_Connect : MonoBehaviour {



        public string Host = "127.0.0.1";



        [Tooltip("TCP port listened by the SmartFoxServer 2X instance; used for regular socket connection in all builds except WebGL")]

        public int TcpPort = 9933;



        [Tooltip("WebSocket port listened by the SmartFoxServer 2X instance; used for in WebGL build only")]

        public int WSPort = 8888;



        [Tooltip("Name of the SmartFoxServer 2X Zone to join")]

        public string Zone = "examplezone";





    SmartFox sfs;



          sfs = new SmartFox ();



          sfs.ThreadSafeMode = false;



         sfs.AddEventListener (SFSEvent.CONNECTION, OnConnection);



        ConfigData cfg = new ConfigData();



        cfg.Host = Host;

        cfg.Port = TcpPort;

        cfg.Zone = Zone;



        sfs.Connect (cfg);

    }

I've removed and reimport smartfox.dll but still the same

What can I do?

Note : I create a new project and import smartfoxserver, its connected to server
