I did the change, but, still get the same error 500 Can't connect to <domain>:443 (connect: Connection refused). The URL we are hitting is external; do we have to add their CA to verify server certificates,$client->setCa('/path/to/ca.file'); or add their SSL cert and provide it to REST::Client, cert => '/path/to/ssl.crt'

#!/usr/bin/perl

use strict;
use warnings;
use REST::Client;
use LWP::UserAgent;

MAIN:
{

my $ua = LWP::UserAgent->new(
    ssl_opts => {verify_hostname => 0},
);

my $client = REST::Client->new(
        timeout => 30,
        useragent => $ua,);

$client->GET(<end point url>);

        #assigning the API response to a variable
        my $response = $client->responseContent();
        print $response."\n";
}
