Alamofire returning status Failure Always

Question

I am using Alamofire in my App. This is my Alamofire request code

let params: [String:AnyObject] = ["email": self.signin_Email.text!, "password": self.signin_Password.text!]

               Alamofire.request(.GET, "http://DomainName/api/App/Sign_Up", parameters: params, encoding:.JSON)
                    .responseJSON {  response  in
                     debugPrint(response)
                }

when i put debugPrint(reponse) what i got is this

[Request]: { URL: http://Domain/api/App/Sign_Up } [Response]: nil [Data]: 0 bytes [Result]: FAILURE: Error Domain=NSURLErrorDomain Code=-1017 "cannot parse response" UserInfo={NSUnderlyingError=0x7ffe0840e700 {Error Domain=kCFErrorDomainCFNetwork Code=-1017 "(null)" UserInfo={_kCFStreamErrorCodeKey=-1, _kCFStreamErrorDomainKey=4}}, NSErrorFailingURLStringKey=http://Domain/api/App/Sign_Up, NSErrorFailingURLKey=http://Domain/api/App/Sign_Up, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-1, NSLocalizedDescription=cannot parse response}

Here i am always getting the response status as Failure. I am not able to figure out what's going on. (using mvc4 as backend). This is the Api method that accepts the above given request and returns a JSON Data

 [System.Web.Http.HttpGet]
    public JsonResult Sign_Up(string email,string password)
    {
        email = email;
        password = password;
        System.Web.Mvc.JsonResult usertoreturn = new System.Web.Mvc.JsonResult();
        SignUpViewModel signupviewmodel = new SignUpViewModel();

                usermodeltocheck.SetPassword(password);
                usermodeltocheck.MembershipDate = DateTime.Now;
                usermodeltocheck.IsMember = true;
                usermodeltocheck.PublicKey = Guid.NewGuid().ToString("N");
                usermodeltocheck.MembershipStatus = true;
                usertoreturn.Data = Helper.UpdateUser(usermodeltocheck);
            }

       usertoreturn.JsonRequestBehavior = System.Web.Mvc.JsonRequestBehavior.AllowGet;

        return usertoreturn;
    }

UPDATE #1 I have created a new method named test that accepts a parameter.The method just returns the parameter value .I tried the sample code available in Github and its working. I am able to get proper response if I am avoiding parameters argument in Alamofire request Method. like

Alamofire.request(.GET, "http://DomainName/api/App/Test", encoding: .JSON).responseJSON{
                    response in
                debugPrint(response)

                }

here I am getting a SUCCESS response. I have updated my code like this

Alamofire.request(.GET, "http://DomianName/api/App/Test?test=testing", encoding: .JSON).responseJSON{
                    response in
                debugPrint(response)

                }

here also I am getting SUCCESS response. The Error occurs when I pass parameter value to the argument parameters parameters: ["test":"testing"]. also I set my parameters like this

let params = ["test":"testing"]
 Alamofire.request(.GET, "http://DomianName/api/App/Test", parameters : params ,encoding: .JSON).responseJSON{
                        response in
                    debugPrint(response)

                    }

in this way also i am getting my response to FAILURE

May be its not an answer you are looking for but for me removing a parameter from Alamofire request method did the trick. Here is the change:

let params : [String:AnyObject] = ["email":self.signin_Email.text!,"password":self.signin_Password.text!]

let request =  Alamofire.request(.GET, "http://DomianName/api/App/Sign_Up", parameters: params).responseJSON{
    response in

    switch response.result{

    case .Success(let data) :

        let json = JSON(data)
        print(json)

    case .Failure(let error):
        print("Error : \(error)" )

    }
}

I have removed encoding:.JSON from my Alamofire request method parameter list and that's it...
