Мой PHP Socket Server продолжает закрываться на Windows Server

Question

Я запустил сервер Socket PHP на Windows Server 2012 R2, выполнив команду: php -q C:\path\to\server.php.Проблема, которая у меня есть, заключается в том, что через несколько часов сервер я не могу подключиться в JavaScript.Я потратил много времени на поиски, чтобы понять это, но поскольку ошибок нет, я не знаю, что искать.Я думал только о том, что он может отключиться из-за неактивности.

//reuseable port
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);

//bind socket to specified host
socket_bind($socket, 0, $port);

//listen to port
socket_listen($socket);

//create & add listning socket to the list
$clients = array($socket);
