Прежде чем кто-то понизит голос и пометит этот вопрос как дубликат, я уже проверил приведенные ниже вопросы, но ни один из них не применим к моему делу;
MSSQL VIA FreeTDS, ODBC и Cpanel Неизвестное имя хост-компьютера (серьезность)2)
php dblib, Ошибка: SQLSTATE [HY000] Неизвестное имя хост-компьютера (уровень серьезности 2)
Иногда я получаю эту ошибку, когда она былараньше работал нормально.
В настоящее время я исправляю это, чтобы перезапустить службу PHP с помощью sudo service php7.0-fpm restart.Но это вернется через несколько дней.Любая идея?
Я использую Laravel 5.3 с версией PHP ниже;
