Answer 1

This error comes from your FTP server when requesting size of the file.

Can you try using this code before downloading the file:

using(Ftp ftp = new Ftp())
{
    ftp.ConnectSSL("ftp.server.com");
    ftp.Login("user", "password");

    ftp.Configuration.DontGetFileSizeBeforeDownload = true;

    ftp.Download("report.txt", @"c:\report.txt");

    ftp.Close();
}
