The message you are getting back suggests that just using OLE won't work, however it is worth trying the simplest approach (just to prove that it won't do it).

use strict;
use Win32::OLE;

my $ie = Win32::OLE->new( 'InternetExplorer.Application' ) 
        or die "error starting IE";
$ie->{visible} = 1;
$ie->navigate( 'https://internal.site.of.doom/' );
sleep(4);
if(!defined $ie->Document())
  {
    print STDERR "Nope that failed as well");
  }
else
  {
    print "We have something back!\n";
  }
