I created a very simple C # console application to test connection in an API, but I can not send the request. I tried with other APIs and they worked, but this specific one I can not. It would be a query in the CartolaFC API (it's commented on in the code below, the other works).
Following code: error generated:

namespace ConsoleAppHttp
{
class Program
{
static void Main(string[] args)
{
RunAsync();
}
static void RunAsync()
{
using (var clientAPI = new HttpClient())
{
//Um dos sites recomendava isso pra corrigir o problema, mas ainda não funciona
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11;
clientAPI.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//string sResponse = clientAPI.GetStringAsync("http://api.cartolafc.globo.com/mercado/status").Result; //Não Funciona
string sResponse = clientAPI.GetStringAsync("http://jsonplaceholder.typicode.com/posts").Result; //Funciona
Console.Write(sResponse);
}
Console.Read();
}
}
}
There is an error generated:

Exceção interna 1:

Would anyone have any idea how I can solve it? Can you reproduce the problem?
