title: Access a Webserver from smartphone
body: <p>I have a C# webserver running on my PC, i can do request to it from a browser and a Console Application (both on the same PC, the same of webserver) and I can access it using Android Emulator too.</p>
  
  <p>Then I have an Android app in C# which should make a simple request (two methods):  </p>
  
  <pre><code>using (var ws = new WebClient())
              {
                  try
                  {
                      Uri uri = new 
                      Uri("http://192.168.137.1:4100/1/2/3/4/5");
                      ws.DownloadStringAsync(uri);
                  }
                  catch (Exception ex)
                  {
                      Console.WriteLine(ex);
                  }
              }
              using (var cl = new HttpClient())
              {
                  HttpResponseMessage res = await cl.GetAsync("http://192.168.137.1:4100/1/2/3/4/5");
                  Console.WriteLine(res.ToString());
              }
  </code></pre>
  
  <p>But i can't access from it.  I'm using <code>Android 6.0.1 (API 23)</code>.<br>
  Some months ago this app was working, so I don't know if it a network problem or a device(smartphone) problem.</p>
  
  <p>Can some one help me?</p>
