PHP error getimagesize failed to open stream: Connection refused - wordpress

Question

I am using FPDF.php. I get an error when I try to create a PDF "FPDF error: Missing or incorrect image file: http://www.example.com/wp-content/uploads/2015/05/image.jpg"
In my error log I get this error:
PHP Warning: getimagesize(http://www.example.com/wp-content/uploads/2015/05/image.jpg): failed to open stream: Connection refused in /home/cluster-sites/2639/c/example.com/public_html/wp-content/themes/nameoftheme/includes/fpdf/fpdf.php on line 1213
I have set allow_url_fopen = ON in php.ini
I think it has something to do with the image path but I'm not sure what. It works fine on my test server.
My code is as follows:
//check if the query_string contains an ID
if(!isset($_REQUEST['id']))
{
header('Location:'.site_url());
exit();
}
//check if the ID is related to a WP_Post
$post = get_post($_REQUEST['id']);
if(empty($post))
{
header('Location:'.site_url());
exit();
}
