I am working on a StackExchange App (Stack App) for Windows 10 ( For **Windows 10 PC/Mobile and Windows 8.1 Mobile** I have a user login set up and using the `WebAuthenticationBroker` in Universal Windows Platform, to get the access_token. This works fine on Windows 10 Desktop. But when it comes to Windows 10 Mobile, The login page Hangs after tapping on `Login with StackExchange`. By the time i am typing this question. Its almost 28 Mins and it is still running. I tried to enter the URL on my Mobile browser ( Microsoft Edge ) and still the same but it works on my Windows 10 Machine and Tablet. Below is the screenshot. If you see it hangs @ this page not giving me option to enter my username and password. [![enter image description here][1]][1] During my last 10 Mins of search on this topic using query strings `Application Hangs`,`Login hangs`,`Authentication Hangs`, `WebBrowser Hangs` i was redirected to [this question][2] Can anyone point me as to what could be the issue? **Part of my **AuthenticationBroker** string str = string.Format("https://stackexchange.com/oauth/dialog?client_id={0}&scope={1}&redirect_uri={2}", client_id, "no_expiry", "https://stackexchange.com/oauth/login_success"); WebAuthenticationResult WebAuthenticationResult = await WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.None, new Uri(str),new Uri("https://stackexchange.com/oauth/login_success")); if (WebAuthenticationResult.ResponseStatus == WebAuthenticationStatus.Success) { RetVal = OutputToken(WebAuthenticationResult.ResponseData); _class = await GetProfileData(RetVal); } [1]: https://i.sstatic.net/QAMZA.png [2]: http://stackapps.com/questions/4244/desktop-login-url-webbrowser-hangs-net-javascript-endless-loop
