Question Web Client timeout?

[LeonLanford]

Hi.. I'm making program to read txt file from website by using system.net.webclient, It can work perfectly in localhost, but when I tried at the hosting, it got timeout after second or third request at

strem = WC.OpenRead(alamat_txt)

I thought the program hang, but after 2 minutes it shows error message saying timeout.. I must close the program and open it again, if I don't close the program, the remote txt file will cannot be opened again..
Is there something I can do to prevent the timout or prevent from reopening the program again to open the remote file?

Here's the code and screenshot..

       Try
            Using WC As New System.Net.WebClient()
                WC.OpenRead(alamat_view)
                strem = WC.OpenRead(alamat_txt)

            Using reader As New System.IO.StreamReader(strem)
                WC.OpenRead(alamat_view)
                strem = WC.OpenRead(alamat_txt)
                Dim line As String = String.Empty
                While reader.Peek >= 0
                    line = reader.ReadLine()
                End While
            End Using
        End Using

        Catch ex As Exception
            MessageBox.Show("Server is busy.. Please try again")
        End Try

Thanks..
