[Rylisma]

Hey ich hab nen Hitfaker erstellet , jedoch wird jede Proxy als Offline nicht funktionieren angezeigt .
Ist es ein Fehler im Code oder in der Proxy ?

Code :

Imports System.Net
Imports System.Threading

Public Class Form1
    Dim HitfakeThread As Thread
    Dim ProxyListe() As String
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim Open As New OpenFileDialog
        If Open.ShowDialog = Windows.Forms.DialogResult.OK Then
            TextBox2.Text = Open.FileName
            ProxyListe = Split(My.Computer.FileSystem.ReadAllText(TextBox2.Text), vbNewLine)
        End If

    End Sub
    Private Sub Hitfake()
        Dim Offline As Integer = 0
        Dim Online As Integer = 0
        Dim Abspeichern As String = Nothing
        Control.CheckForIllegalCrossThreadCalls = False
        For Each proxy As String In ProxyListe
            Try
                Dim IP_Adresse As String
                Dim Port As Integer
                IP_Adresse = Split(proxy, ":")(0)
                Port = CType(Split(proxy, ":")(1), Integer)
                Dim WProxy As New WebProxy(IP_Adresse, Port)
                Dim WClient As New WebClient
                WClient.Proxy = WProxy
                WClient.DownloadString(New Uri(TextBox1.Text))
                Online += 1
                Abspeichern &= proxy & vbNewLine
                Offline += 1
            Catch ex As Exception
                ProgressBar1.Value += 1
                Label9.Text = ProgressBar1.Value.ToString & "/" & ProxyListe.Count.ToString
                Label8.Text = Online.ToString
                Label7.Text = Offline.ToString
            End Try
        Next
