I don't see your comparison between your working snippet, and your failing sub. The failing sub dosn't resemble the working snippet at all. This snippet works on linux, you might try to substitute your working snippet and see if it goes. 
#!/usr/bin/perl
use strict;
use warnings;
use Net::SSH::Perl;
use Tk;

my $mw = MainWindow->new;

my $text = $mw->Text();
$text->pack;

$text->insert('end',"Net::SSH::Perl Test\n");

$mw->Button(
    -text    => "SSH",
    -command => \&do_ssh )->pack;

$mw->Button(
    -text    => "Exit",
    -command => sub{exit} )->pack;

MainLoop;

sub do_ssh{
  my $user = "z";
  my $password = "ztest";
  my @hosts = qw(localhost);

    foreach my $host (@hosts){
       my $cmd = "/usr/bin/uptime";
       my $ssh = Net::SSH::Perl->new( $host, 
                    port => 22 ,
            protocol => 2,
       #            debug => 1,
            
            );
       $ssh->login($user,$password);

      my($out) = $ssh->cmd($cmd);
      my ($time,$uptime) = (split /\s+/,$out)[1,3];
      chop $uptime;
      $text->insert('end', "$out\n");
      $text->insert('end', "$host has been up $uptime\n");
    }
 
}
