I have a PHP CURL script that refuses to work

PHP & CURL work everywhere on the site but not in this new script.
I've even created a standalone script and it still fails.
The script is here and is self explanatory: It just want to retrieve the page content from a URL.
I guess I've done something daft...
$25 / £20 to the first person to fix this!
Here's the script:

<?php
$thisLink = 'https://www.zandax.com';

$url = $thisLink;
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 50);
curl_setopt($curl, CURLOPT_TIMEOUT, 50);
$output = curl_exec($curl);

echo 'OUTPUT: ' . $output ;
