Access a Webserver from smartphone
0
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.
Then I have an Android app in C# which should make a simple request (two methods):
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());
But i can't access from it. I'm using Android 6.0.1 (API 23).
Some months ago this app was working, so I don't know if it a network problem or a device(smartphone) problem.
Can some one help me?

Where is the Android app executed? On a physical smartphone? Or an emulator on your PC?

So you run the server-app on your pc on port 4100 and the app on your physical device? In this case this sounds like a networking problem. Are both devices (pc and smartphone) in the same subnet, is port 4100 on your pc listening on all incoming ip-ranges, is your firewall configured to allow incoming tcp traffic on port 4100, do you have a proxy configured, ...?

They are in the same network (I'm using wi-fi). I've set a new incoming rule for port 4100 and I've disabled PC Firewall just in case. And I'm not using a proxy.
