(Go) ConnectFailReason

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 Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    ftp := chilkat.NewFtp2()

    ftp.SetHostname("ftp.example.com")
    ftp.SetUsername("login")
    ftp.SetPassword("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.
        // 
        failReason := ftp.ConnectFailReason()

        fmt.Println("connect fail reason = ", failReason)

        fmt.Println(ftp.LastErrorText())
        ftp.DisposeFtp2()
        return
