Vim::login(service_url =>)

Hi

I m trying to make a script for retrieving some informations about the esxi

here is my problem

I have two variables:

$opt_H and $url

$url = "https://".$opt_H."/sdk/webServer";

If I use $url with a variable the connexion doesn't work

Can't connect to XXXX.XXX.XXX.XX:443 (Connection refused)

LWP::Protocol::https::Socket: connect: Connection refused at /usr/lib/perl5/site_perl/5.8.8/LWP/Protocol/http.pm line 51.

If i change the variable and put the real ip address of the esxi it works

I don't understand, what I am doing wrong ?

I use these libraires:

$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0;
use strict;
use warnings;
use Getopt::Long;
use utils qw($TIMEOUT %ERRORS &print_revision &support);
use VMware::VIRuntime;
use VMware::VILib;

thanks in advance
