New Post: PortForwading Bug

I read last comments, but I'm not able to solve.

I do this next test.
I made a TEMP database on two sql servers availables with 2 freeSSH servers for each network.
I create a temp users for SSH server
With a blank Windows form project I draw 2 buttons and 2 richtectbox. I used VB.

From Click event on button 1 I write to conenct to server 1

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        RichTextBox1.AppendText("Connecting...." & vbNewLine)

      

        Dim client As SshClient = New SshClient("77.73.166.66", 1443, "tempuser", "tempuser")
        Try
            client.Connect()
            RichTextBox1.AppendText("Connected to 77.73.166.66:1443" & vbNewLine)
            Dim fw As ForwardedPortLocal = New ForwardedPortLocal("127.0.0.1", 14444, "192.168.1.3", 1433)
            client.AddForwardedPort(fw)
            fw.Start()

            Dim query As String = "select * from temp"
            Dim CadenaDEconexion As String = "data source =127.0.0.1,14444; initial catalog = TEMP; user id = tempuser; password = tempuser; MultipleActiveResultSets=True"

            Dim cnn As New SqlConnection(CadenaDEconexion)
            Dim cmd As New SqlCommand
            Dim rdr As SqlDataReader
            cnn.Open()
            cmd.Connection = cnn
            cmd.CommandText = query
            rdr = cmd.ExecuteReader

            While rdr.Read
                RichTextBox1.AppendText(rdr(0) & " " & rdr(1) & vbNewLine)
            End While

            rdr.Close()
            cnn.Close()

            fw.Stop()
            client.RemoveForwardedPort(fw)
            client.Disconnect()
        Catch ex As Exception

        End Try
    End Sub

On the Click from button2 to connect to server 2

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        RichTextBox2.AppendText("Connecting...." & vbNewLine)
        Dim client As SshClient = New SshClient("77.73.161.57", 1443, "tempuser", "tempuser")
        Try
            client.Connect()
            RichTextBox2.AppendText("Connected to 77.73.161.57:1443" & vbNewLine)
            Dim fw As ForwardedPortLocal = New ForwardedPortLocal("127.0.0.1", 14444, "192.168.1.3", 1433)
            client.AddForwardedPort(fw)
            fw.Start()

            Dim query As String = "select * from temp"
            Dim CadenaDEconexion As String = "data source =127.0.0.1,14444; initial catalog = TEMP; user id = tempuser; password = tempuser; MultipleActiveResultSets=True"

            Dim cnn As New SqlConnection(CadenaDEconexion)
            Dim cmd As New SqlCommand
            Dim rdr As SqlDataReader
            cnn.Open()
            cmd.Connection = cnn
            cmd.CommandText = query
            rdr = cmd.ExecuteReader

            While rdr.Read
                RichTextBox2.AppendText(rdr(0) & " " & rdr(1) & vbNewLine)
            End While

            rdr.Close()
            cnn.Close()

            fw.Stop()
            client.RemoveForwardedPort(fw)
            client.Disconnect()


        Catch ex As Exception

        End Try
    End Sub

TEST steps:

I Start application:
Button1 Connect to Server1----- OK
Query restult------>
Connected to 77.73.166.66:1443
Full 1
My name
Close application

Start application
Button2 Connect to server2 ----- OK
Query result ----->
Full 2
My name 2
Close application


Start application
Button1 Connect to server 1 ---> ok
Query Result --->
Full 1
My name
WITHOUT close application
Button2 Connecto to server 2 ---> Client.IsConnected shows True
but...Query result--->
Full 1
My name


Returns the results from Client1.

You can use my servers data to try if you need.

What I'm doing wrong??
