Hello I'm trying to connect my PC to remote PC with socket but I have error 40006.
I'm sure that there is not connection.

Here is code:

SERVER ..............

Option Explicit
Dim iSockets As Integer
Dim sServerMsg As String
Dim sRequestID As String
Dim Income() As String

Private Sub Form_Load()
    lblHostID.Caption = Socket(0).LocalHostName
    lblAddress.Caption = Socket(0).LocalIP
    Socket(0).LocalPort = 1
    sServerMsg = "Listening to port: " & Socket(0).LocalPort
    List1.AddItem (sServerMsg)
End Sub

Private Sub socket_ConnectionRequest(index As Integer, ByVal requestID As Long)
'Check if there is a connection request, confirm that it is from the right port then allow connection
    sServerMsg = "Connection request id " & requestID & " from " & Socket(index).RemoteHostIP
  If index = 0 Then
    List1.AddItem (sServerMsg)
    sRequestID = requestID
    iSockets = iSockets + 1
    lblConnections.Caption = iSockets
    Load Socket(iSockets)
    Socket(iSockets).LocalPort = 1001
    Socket(iSockets).Accept requestID
  End If
End Sub

Private Sub socket_Close(index As Integer)
    'close a particular connection and decrease the number of concurrent connections
    sServerMsg = "Connection closed: " & Socket(index).RemoteHostIP
    List1.AddItem (sServerMsg)
    Unload Socket(index)
    iSockets = iSockets - 1
    lblConnections.Caption = iSockets
End Sub

Private Sub socket_DataArrival(index As Integer, ByVal bytesTotal As Long)
Dim strData As String
    ' get data from client
    Socket(index).GetData strData
    sServerMsg = strData
    List1.AddItem (sServerMsg)
End Sub

Public Sub Readout(sItem As String, index As Integer)
Dim strData As String
    strData = Now()
    'send data to client
    sServerMsg = strData & " -> " & Socket(index).RemoteHostIP
    List1.AddItem (sServerMsg)
    Socket(index).SendData strData
End Sub

Public Sub InputBack(sAdder() As String, index As Integer)
End Sub


Option Explicit
Private Sub cmddSend_Click()
    If Winsock1.State = sckConnected Then
        Winsock1.SendData Now()
        'shpCond.FillColor = QBColor(14)
        Label3.Caption = "Sending Data"
        'shpCond.FillColor = QBColor(4)
        Label3.Caption = "Not currently connected to Server"
    End If
End Sub

Private Sub cmdClose_Click()
    shpCond.FillColor = QBColor(4)
End Sub

Private Sub cmdConnect_Click()
    Winsock1.RemoteHost = "" 'My host IP
    Winsock1.RemotePort = 2
    If Winsock1.State = 6 Then
        'attempting to connect
        shpCond.FillColor = QBColor(14)
    ElseIf Winsock1.State = 7 Then
        'connection has been made
        shpCond.FillColor = QBColor(10)
        cmdConnect.Enabled = False
        'We could not connect
        shpCond.FillColor = QBColor(4)
        Label3.Caption = "Not Connected to " & Winsock1.RemoteHost
        cmdConnect.Enabled = True
    End If
End Sub

Private Sub Timer1_Timer()
    'check connection status of  client
    Checkstate (Winsock1.State)
End Sub

Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
Dim sData As String
    Winsock1.GetData sData
    txtArrival.Text = sData
    shpCond.FillColor = QBColor(10)
End Sub

Private Sub Winsock1_SendComplete()
    Label3.Caption = "Send Complete"
End Sub

I try also with other example program, but nothing.
Help, please

Here's a brief discussion about that problem

Another possibility is the firewall on the pc you want to connect to is blocking your program.

Firewall is OK. Could it be the port?
