I have used a webbrowser object in my asp.net code to retrieve content from websites. the code runs absolutely fine when execute from visual studio, but after hosting, there is no response. it shows "connecting.... " on the browser tab and loads nothing! I have pasted my code below for your understanding.

===========Webbrowser code=============

Dim url As String = ""
url = "https://google.com/patents/" & ListBox1.SelectedItem.ToString()

Dim thread As New Thread(Sub()
                             Using browser As New WebBrowser()
                                 browser.ScrollBarsEnabled = False
                                 browser.ScriptErrorsSuppressed = True
                                 browser.AllowNavigation = True
                                 browser.Navigate(url)
                                 AddHandler browser.DocumentCompleted, New WebBrowserDocumentCompletedEventHandler(AddressOf DocumentCompleted)
                                 While browser.ReadyState <> WebBrowserReadyState.Complete
                                     System.Windows.Forms.Application.DoEvents()
                                 End While
                             End Using
                         End Sub)
thread.SetApartmentState(ApartmentState.STA)
thread.Start()
thread.Join()
=====================================
    Private Sub DocumentCompleted(sender As Object, e As WebBrowserDocumentCompletedEventArgs)
        Dim browser As WebBrowser = TryCast(sender, WebBrowser)
        Dim webCont As String = browser.Document.Body.InnerHtml
