Делаю запрос

curl -X POST --header 'Content-Type: application/json' --header 'Accept:
application/json' там дальше запрос и URL

В логах вижу запись с 200 кодом

Дальше делаю еще раз запрос
curl -X POST --header 'Content-Type: application/json' --header 'Accept:
application/json' там дальше запрос и URL
И получаю ответ curl: (52) Empty reply from server

А в логах nginx пусто!

Изменил error_log путь до лога debug;
Остановил nginx. Запустил nginx-debug.


И все равно пусто.

Что может быть?
