PHP’s fsockopen() problems
The PHP function fsockopen() may not work because of firewall restrictions on the outgoing connections.
In such cases the port required for the outgoing connection should be opened. You can request this by opening a ticket through your User Area -> Support -> Report Other Technical Issues.
