you have to change your method something like this

public IActionResult Start()
    {


     var jsonRequest = Json(new { ServerId = "1", ServerPort = "27015" }).Value.ToString();
                    HttpClient client = new HttpClient();
                    client.BaseAddress = new Uri("http://13.77.102.81/api/mta/start ");
                    client.DefaultRequestHeaders
                          .Accept
                          .Add(new MediaTypeWithQualityHeaderValue("application/json"));//ACCEPT header

                    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "relativeAddress");

                    request.Content = new StringContent(jsonRequest,
                                                        Encoding.UTF8,
                                                        "application/json");//CONTENT-TYPE header

                    client.SendAsync(request)
                          .ContinueWith(responseTask =>
                          {
                               //here your response 
                              Debug.WriteLine("Response: {0}", responseTask.Result);
                          });
        return View();
    }

and here the response

Response: StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
  Connection: keep-alive
  Date: Sun, 26 Feb 2017 21:43:26 GMT
  Server: nginx/1.4.6
  Server: (Ubuntu)
  Content-Length: 0
}

so your server is not running or your proxy does filters on requests :)
