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:

Chilkat.Ftp2 ftp = new Chilkat.Ftp2();

bool success;

//  Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    MessageBox.Show(ftp.LastErrorText);
    return;
}

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

//  Connect and login to the FTP server.
success = ftp.Connect();
if (success != true) {

    //  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.
    // 
    int failReason;
    failReason = ftp.ConnectFailReason;

    textBox1.Text += "connect fail reason = "
         + Convert.ToString(failReason) + "\r\n";
    textBox1.Refresh();

    MessageBox.Show(ftp.LastErrorText);
    return;
