C # SimpleTcpServer Does Not Recognize IPAddress

Question

I am using SimpleTcpServer in a Windows Forms Application and when I use an IPAddress 10.10.5.27 Port 8080 gives Exception System.Net.Sockets.SocketException

The Form starts with the following statement below:

private void Form1_Load(object sender, EventArgs e)
    {
        this.Hide();
        this.WindowState = FormWindowState.Minimized;

        server = new SimpleTcpServer
        {
            //server.Delimiter = 0x13;
            StringEncoder = Encoding.UTF8
        };

        server.DataReceived += Server_DataReceived;

        IniciaServico();
    }

After the Form gives a Load executes the StartService giving exception on the server.Start (ip, 8080) line;

private void IniciaServico()
    {

        IPAddress ip = IPAddress.Parse("10.10.5.27");
        server.Start(ip, 8080);

        Habilita(false);

        txtStatus.Text += "Serviço ativo...";
    }

Note to use Ip 127.0.0.1 on port 8910 works, but I need to communicate with this Ip 10.10.5.27

     

Answer 1

The first thing I would try is to connect to the 10.10.5.27 with telnet from a command prompt.

telnet 10.10.5.27 8080

if you can not connect I would verify the firewall is not blocking access and also verify the service is available no port 8080.
