HttpClient getting timed out even after setting Timeout.Infinite

i am using HttpClient to fetch the data from the server in Xamarin Forms using following code

public  Task<HttpResponseMessage> sendData(String url,String jsonData)
    {

        using (var client = new HttpClient())
        {

            var jsonContent = new StringContent(jsonData, System.Text.Encoding.UTF8, "application/json");

            client.Timeout = TimeSpan.FromMilliseconds(Timeout.Infinite);
            client.BaseAddress = new Uri(baseAddress);

            return  client.PostAsync(new Uri(url, UriKind.Relative), jsonContent);
        }
    }

Here i have used Timeout.Infinite as webservice is taking around 4 mins to return the response but although i have set the Timeout.Infinite app is throwing Operation time out exception. I tried with the various timeouts as well like 240000ms but still getting operation timeout.

However, when i try to fire the same request in postman it is working but yes returning the response after 4 mins of time. As it is a third party api, we can not change anything there.

can anyone please suggest how can i forced the HttpClient to hold more for the response.

Detail exception i am getting 

{System.Net.Http.HttpRequestException: An error occurred while sending the request ---> System.Net.WebException: The operation has timed out.

I have tried following code for Android and iOS and it seems working and can wait little longer on socket while fetching data using webservice

in Xamarin.Android following code is used and exposed it using DependencyService

 public HttpClientHandler GetHttpClientHandler()
        {

            Xamarin.Android.Net.AndroidClientHandler http = new Xamarin.Android.Net.AndroidClientHandler();
            http.ReadTimeout = TimeSpan.FromMinutes(5.0);   


            return http;
        }

in Xamarin.iOS following code is used and exposed it using DependencyService 

HttpMessageHandler IHttpHandler.GetHttpHandler()
{


    NSUrlSessionConfiguration sessionConfig = NSUrlSessionConfiguration.DefaultSessionConfiguration;
    sessionConfig.TimeoutIntervalForRequest = 300;
    sessionConfig.TimeoutIntervalForResource = 300;
    sessionConfig.WaitsForConnectivity = true;


    NSUrlSessionHandler sessionHandler = new NSUrlSessionHandler(sessionConfig);

    return (sessionHandler);
}

Note : in case of iOS it will return HttpMessageHandler

Usage in Xamarin.Forms

   HttpClient client = new HttpClient(DependencyService.Get<IHttpClientHandler>().GetHttpClient());

However, there is one catch over here , in case of iOS if app is fetching the data using HttpClient and if user locks the screen by pressing the lock button in iPhone then the service gets immediately interrupted and throws Connection Interrupted and socket gets closed. if anyone could find any solution to this then feel free to post

Try using the InfiniteTimeSpan from the System.Threading.Timeout namespace.

client.Timeout = System.Threading.Timeout.InfiniteTimeSpan;

I'm using it on my Xamarin projects, and it appears to be to working fine.
