php curl not working on ubuntu server got http_code 403

I using curl php to get data from another server. When I test on localhost it working fine.

These are my testing code

<?php

$data = file_get_contents_curl('http://marketplace.envato.com/api/edge/new-files:graphicriver,web-elements.json');

function file_get_contents_curl($url) 
{
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.2 Safari/537.36");
	curl_setopt($ch, CURLOPT_HEADER, 0);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
	$data = curl_exec($ch);
	curl_close($ch);
	return $data;
}

?>

I got this error when using on vps server
