R – Windows Mobile Web Services – works while tethered, not while using cell data network

asp.netnetweb serviceswindows-mobile

I've written an ASP.NET web service that I would like a .NET 3.x application running under Windows Mobile 6.1 to communicate with.

When the phone is connected to a desktop via USB/ActiveSync it can communicate with the web service flawlessly.

When I place the phone on the cell network (unplug the USB cable) it is not able to communicate with the web service. I get a System.Net.WebException -> Unable to connect to remote server. System.Net.Sockets.SocketException -> A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

When I attempt to browse to the ASMX page via the mobile browser (Opera), while on the cell network, it connects and renders the description page perfectly.

Any ideas?

I solved this before seeing GenericTypeTea's comment - but good job GTT, right on the money.

Apparently when you use the GUI in VS to add a web reference it converts the domain address into an IP address. How ridiculous.

Anyhow.. solved.

Try connecting to the same server/resource in your code as in IE.

port should be 2195

also change SslProtocols.Ssl3 to SslProtocols.Tls

    public static void pushMessage(string deviceID)
    {
        int port = 2195;
        String hostname = "gateway.push.apple.com";
        String certificatePath = System.Web.Hosting.HostingEnvironment.MapPath("pushkey.p12");
        X509Certificate2 clientCertificate = new X509Certificate2(System.IO.File.ReadAllBytes(certificatePath), "yourPassword");
        X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate);

        TcpClient client = new TcpClient(hostname, port);
        SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);

        try
        {
            sslStream.AuthenticateAsClient(hostname, certificatesCollection, SslProtocols.Tls, false);
            MemoryStream memoryStream = new MemoryStream();
            BinaryWriter writer = new BinaryWriter(memoryStream);
            writer.Write((byte)0);
            writer.Write((byte)0);
            writer.Write((byte)32);

            writer.Write(HexStringToByteArray(deviceID.ToUpper()));
            String payload = "{\"aps\":{\"alert\":\"" + "Hi,, This Is a Sample Push Notification For IPhone.." + "\",\"badge\":1,\"sound\":\"default\"}}";
            writer.Write((byte)0);
            writer.Write((byte)payload.Length);
            byte[] b1 = System.Text.Encoding.UTF8.GetBytes(payload);
            writer.Write(b1);
            writer.Flush();
            byte[] array = memoryStream.ToArray();
            sslStream.Write(array);
            sslStream.Flush();
            client.Close();
        }
        catch (System.Security.Authentication.AuthenticationException ex)
        {
            client.Close();
        }
        catch (Exception e)
        {
            client.Close();
        }
    }
