Problem with WebBrowser

I have a problem trying to open a page made in Java from a device that is on my local network.

Code:

namespace RFIDIsaiv._1
{
    public partial class WebConf : Form
    {
        public WebConf()
        {
            InitializeComponent();
        }

        private void WebConf_Load(object sender, EventArgs e)
        {
            webBrowser1.Navigate(new Uri("http://172.16.2.253:3161/index.html"));
        }

    }
}
