The ConnectFailReason property can be examined to determine the reason why the Connect method failed. The possible values are listed in the source code below:

Dim ftp As New Chilkat.Ftp2()

Dim success As Boolean

'  Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial")
If (success <> true) Then
    MsgBox(ftp.LastErrorText)
    Exit Sub
End If


ftp.Hostname = "ftp.****.com"
ftp.Username = "****"
ftp.Password = "****"

'  Connect and login to the FTP server.
success = ftp.Connect()
If (success <> true) Then

    '  The possible failure reasons are:
    '  0 = success
    '  Non-SSL socket fail reasons:
    '   1 = empty hostname
    '   2 = DNS lookup failed
    '   3 = DNS timeout
    '   4 = Aborted by application.
    '   5 = Internal failure.
    '   6 = Connect Timed Out
    '   7 = Connect Rejected (or failed for some other reason)
    '  SSL failure reasons:
    '   100 = Internal schannel error
    '   101 = Failed to create credentials
    '   102 = Failed to send initial message to proxy.
    '   103 = Handshake failed.
    '   104 = Failed to obtain remote certificate.
    '  300 = asynch op in progress
    '  301 = login failure.
    ' 
    Dim failReason As Long
    failReason = ftp.ConnectFailReason

    TextBox1.Text = TextBox1.Text & "connect fail reason = " _
         & failReason & vbCrLf
    TextBox1.Refresh()

    MsgBox(ftp.LastErrorText)
