I noticed a couple of errors. Looking at your debug output:

host.fqdn.tld: sftp: Sending SSH2_FXP_INIT

That's telling you that Net::SFTP, which underlies Net::SFTP::Recursive, only supports SSH2 and not SSH1. So takeout the protocol => '2 1' because it isn't necessary.

Second, I'd change debug => 'true' to debug => 1 because it's easier to read. Then your script should start something like this: 

#!/usr/bin/perl

use strict;
use warnings;
use Net::SFTP::Recursive;
use Data::Dumper;

my $host = '127.0.0.1';

my %cfg = (
    user     => 'user',
    password => 'password',
    debug    => 1,
);

my $sftp = Net::SFTP::Recursive->new($host, %cfg);

From what I can see, I think that your server expects SSH1, but it's not getting it:-).
