Laravel fsockopen (): php_network_getaddresses

У меня есть проект Laravel с внешними файлами php. Я уже включил их в свой контроллер успешно. Цель этого файла — проверить, является ли адрес электронной почты действительным (реальным) или нет. (если у вас есть другой путь в Ларавеле, пожалуйста, сообщите)

ниже находятся файлы:
CCheckMail.php

Я включаю их в свой контроллер и использую их, как показано ниже:

    $pricesClass = new CCheckMail();
//$email2 =  ['[email protected]'];
$email2 =  "[email protected]";
$prices = $pricesClass->execute ($email2);
return view('pages.home', compact('prices'));

Я использую XAMPP для запуска моего приложения Laravel. Это дало мне эту ошибку

ErrorException (E_WARNING) fsockopen (): php_network_getaddresses:
Сбой getaddrinfo: имя узла или имя сервера не предоставлено или не известно

Думаю проблема из php файла не из laravel?
