Your stated versions of Perl (5.10) and Net::FTPSSL (0.27) are very old. It's therefore likely that your versions of IO::Socket::SSL and Net::SSLeay (and probably openssl) are very old too. You might consider upgrading, or at least running the code on a much newer system. It's possible that the TLS versions permitted on the server are newer than your very old client will support. 🦛	[reply]
