Ошибка соединения с базой из backend (из frontend работает отлично)

Приветствую всех.
Есть advanced-приложение. В frontend и backend настройки к базе одинаковые и хранятся в /common/config/main.php и /common/config/main.local.php
В /frontend/config/main.php и /backend/config/main.php (main и main-local) никаких настроек базы нет.

Локально все работает. Но когда скопировал на сервер, то при попытке обращении к БД backend-отказывается работать и пишет ошибку (frontend работает отлично):

Код (Text):

1. Database Exception – yii\db\Exception
2.  
3. SQLSTATE[HY000] [2002] No such file or directory
4. ↵
5. Caused by: PDOException

Из-за чего такое? Единственный момент: таблица к которой обращается frontend с подчеркиванием имеет вид: name_name, соответственно модель ActiveRecord для работы с ней называется NameName. Пробовал убирать подчеркивание в названии таблицы - все то же самое.
Перерыл в гугле многие форумы и не нашем ответа на вопрос. Из-за чего такое может быть?

 

Вот весь код (не могу понять куда смотреть):
