php curl getting back empty content - php

Question

Hey there I have been looking around for a solution for the problem for a while now, but no luck so far...basically, I want to pull down a page content using curl in PHP. And the following is the code
static function getContent($url) {
// pull down the content that the url pointing to
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_VERBOSE, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_BINARYTRANSFER, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_AUTOREFERER, true);
curl_setopt($curl, CURLOPT_USERAGENT, Constants::$USER_AGENT_CHROME);
$cookie = realpath(Constants::$ROOT_DIR . Constants::$COOKIE);
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($curl, CURLOPT_FAILONERROR, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);
// curl_setopt ($curl, CURLOPT_CAINFO, dirname(__FILE__).'/cacert.pem');
$content = curl_exec($curl);
curl_close($curl);
return $content;
}
And the call to the function with the following url always returns me empty content and had no problem so far with other different urls (from different domains) that I tried.
$url = 'https://www.etsy.com/listing/150723421/iretrofone-20-steampunk-silver';
Any reason why?
[EDIT] I ran this script on Amazon Linux, something might be missing on the machine such that the issue got exposed. The two answers so far didn't work with me.
[EDIT] The following is the curl_getinfo output

Try this code, its working with no cookie.
<?php
function getContent($url) {
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
$data = curl_exec($curl);
curl_close($curl);
return $data;
}
$url = 'https://www.etsy.com/listing/150723421/iretrofone-20-steampunk-silver';
echo $a = getContent($url);
?>
