Suddently my app stop work

[tabutnas]

Hello,

i dont know why my app stop work, when i try to connect by ZendekApi_v2 Version runtime "v4.0.30319".

First at all i wanted to know why the object "api" don't have any method to know if conect o whatever fail.

And the problem is when i try to connect to my domain and credentials, api.Tickets.CreateTicket, send the follow inner exception; "Object reference not set to an instance of an object."

This is my code;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
using NUnit.Framework;
using ZendeskApi_v2;
using ZendeskApi_v2.Requests;
using ZendeskApi_v2.Extensions;
using ZendeskApi_v2.Models.Users;
using ZendeskApi_v2.Models.Shared;
using ZendeskApi_v2.Models.Constants;
using ZendeskApi_v2.Models.Tickets;
using OliviaSistemas.Utils.ZendeskInterface.Helpers;

namespace ZendeskInterfaceTestApp
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                Console.WriteLine("TESTING");
                CreateSampleTickets01(10);
                Console.WriteLine("Done");
            }
            catch (Exception ex)
            {
                Console.WriteLine("ERROR e: {0} Json MSG: {1}", ex.Message, ex.Data["jsonException"]);
               // Assert.IsTrue(ex.Message.Contains("Email: cannot be blank") && ex.Data["jsonException"] != null && ex.Data["jsonException"].ToString().Contains("Email: cannot be blank"));

            }
            finally
            {
                Console.ReadKey();
            }
        }

    internal static void CreateSampleTickets01(int count = 10)
        {
            String page = "";
ZendeskApi_v2.ZendeskApi api = new ZendeskApi_v2.ZendeskApi(
                "https://****.zendesk.com/api/v2",
                "****@****.net",
                "****",
                "****");

            for (int i = 0; i < count; i++)
            {
                System.Threading.Thread.Sleep(1000);

                String subject = "Olivia Test - " + DateTime.Now.ToString();
                api.Tickets.CreateTicket(new Ticket
                {
                    Requester = new Requester { Email = "[email protected]", Name = " Marc Ibañez" },
                    Type = TicketTypes.Question,
                    Subject = subject,
                    Comment = new Comment { Body = subject + " (this is a test)" }
                });

                Console.WriteLine("Ticket created: {0}", subject);
            } }

Thanks in advance

Based on my reading of the sample that you have listed you may be having a TLS/SSL please see issues #339 for how to fix that.

If you find that is not the issue. Please post the full stack trace for the exception.

Thanks @mozts2005 ,

the problem was here -> https://support.zendesk.com/hc/en-us/articles/360000710347-Removal-of-support-for-TLS-protocol-versions-1-0-and-1-1

So the solution is enable suported TLS, in my case i enable TLS 1.2 on my program and work well now :)

I apply the following code for do that
