Description Marko 2015-11-20 16:37:18 UTC
Mono does not like the Cloudflare SSL certificate and throws an exception.

Test code:

			Task.Run (async () => {
				try 
				{
					using(HttpClient client = new HttpClient { Timeout = TimeSpan.FromSeconds(5) }) 
					{
						using(var responseMessage = await client.GetAsync (new Uri("https://markobl.com")).ConfigureAwait(false)) 
						{
							var content = await responseMessage.Content.ReadAsStringAsync ().ConfigureAwait(false);
						}
					}
				}
				catch (Exception ex) 
				{
					Console.WriteLine (string.Format("Sending request failed: {0}\n", ex));
				}
			}).Wait ();
