Настройка PHP:

[ATTACH]160623[/ATTACH]

А что это у Вас в логах один и тот же IP:

37.55.187.217

Если IP не Ваш то на сервере по SSH команду:

iptables -I INPUT -s 37.55.187.217 -j DROP

adel92, это мой IP!

Borodun, лучше error_log апача (бекенда) выложите.

Напишите в ЛС, если предоставите доступы то посмотрим на самом сервере.

Вот это вроде то что нужно, но не факт, что эти настройки применены для ваших сайтов. Если там в режиме CGI сайты, то нужно смотреть php.ini юзера.

А второе - еще у nginx есть что-то вроде client_max_body_size , но он обычно 128 Мб по-умолчанию на серверах под управлением ISPmanager.

И у nginx опять же таймауты есть, что-то вроде proxy_send_timeout. Если в него не укладывается импорт по времени, то соответственно тоже может быть проблема.
