Q:

LinqToTwitter I can't catch tweets

I am trying to fetch tweets using the example on GitHub, but I get an error "The underlying connection was closed: An unexpected error occurred in a submission". I can not understand. At first, I created the application on Twitter and took the keys generated by Twitter and added it to the application. I had doubts about 2 attributes that I don't know what they will be used for, and I don't know if they are causing problems:
1 - Website URL - I created a website on Wix to fill this field, but I didn't understand its use, since I just want to read tweets in a desktop application.
2 - Callback URL - Initially I didn't put anything, then I saw in a post that it was to put http://127.0.0.1/ I ran the application with this information, but again I don't know what it is for, because I'm going to get tweets from a desktop application .
Here are the code used and the error received!

using System;
using System.Linq;
using System.Threading.Tasks;
using LinqToTwitter;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main()
        {        
            MainAsync().Wait();
        }
        static async Task MainAsync()
        {
            var auth = new SingleUserAuthorizer
            {

                CredentialStore = new InMemoryCredentialStore()
                {
                    ConsumerKey = "MyConsumerKey",
                    ConsumerSecret = "MyConsumerSecret",
                    OAuthToken = "MYOAuthToken",
                    OAuthTokenSecret = "MYOAuthTokenSecret"
                }
            };
            var twitterCtx = new TwitterContext(auth);

            var searchResponse = await (from search in twitterCtx.Search
                                        where search.Type == SearchType.Search 
                                        &&  search.Query == "flamengo"
                                        select search).SingleOrDefaultAsync();

            if (searchResponse != null && searchResponse.Statuses != null)
                searchResponse.Statuses.ForEach(tweet =>
                    Console.WriteLine(
                        "User: {0}, Tweet: {1}",
                        tweet.User.ScreenNameResponse,
                        tweet.Text));
        }
    }
}

A:

This looks similar to the question we resolved here, where the problem was needing to set to TLS 1.2 because it was an older .NET version:
Visual Studio 2015 - Debug with HTTP connection problems
