Maybe when your tcplistener disconnects it then reconnects too quickly not allowing the logical port it uses in the IP stack to reset or something.

Although I don't remember seeing that issue with my code below though maybe it did occur and I didn't notice the error in the RichTextBox or perhaps I added the System.Threading.Thread.Sleep code before the Button1.PerformClick entry because it was happening. I don't remember now.

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Try
            Dim ipAddress As IPAddress = ipAddress.Parse(TextBox1.Text)
            Dim portNumber As Integer = TextBox2.Text
            Dim tcpListener As New TcpListener(ipAddress, portNumber)
            tcpListener.Start()
            RichTextBox1.AppendText("Waiting for connection..." & vbCrLf)
            Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient()
            RichTextBox1.AppendText("Connection accepted." & vbCrLf)

            Dim FileSizeAndName As NetworkStream = tcpClient.GetStream()
            Dim bytes(tcpClient.ReceiveBufferSize) As Byte
            FileSizeAndName.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))
            Dim clientdata As String = Encoding.ASCII.GetString(bytes)

            Dim Split() As String
            Dim delimiterStr As String = "/"
            Dim delimiter As Char() = delimiterStr.ToCharArray()
            Split = clientdata.Split(delimiter, 3)

            Dim File As NetworkStream = tcpClient.GetStream()
            Dim FileLength(CInt(Split(0) - 1)) As Byte
            File.Read(FileLength, 0, CInt(Split(0) - 1))
            My.Computer.FileSystem.WriteAllBytes(TextBox3.Text & "\" & Split(1), FileLength, False)
            Label6.Text = TextBox3.Text & "\" & Split(1)

            Dim responseString As String = "Connected to server."
            Dim sendBytes As [Byte]() = Encoding.ASCII.GetBytes(responseString)
            File.Write(sendBytes, 0, sendBytes.Length)

            RichTextBox1.AppendText(vbCrLf & "Message Sent /> : " & responseString)
            tcpClient.Close()
            tcpListener.Stop()
            RichTextBox1.AppendText("exit")
        Catch ex As Exception
            RichTextBox1.AppendText(ex.Message)
        End Try
        System.Threading.Thread.Sleep(200)
        Button1.PerformClick()
End Sub

Most probable culprit to be the config file . Can you replace your previous config file  and check if error appears?
