Я использую Centos 7 с Nginx и SSL от letsencrypt для использования в качестве прокси-сервера для jenkins на той же капле. Все работало до того момента, когда я попытался прокси-сервер Дженкинс ..., который выдал ошибку 502 Bad Gateway. Блок сервера находится ниже, есть идеи, почему это происходит?

Вот несколько строк, извлеченных из журнала ошибок nginx:
2016/05/12 11:43:03 [error] 2514#0: *1 no resolver defined to resolve localhost, client: xxx.xxx.xxx.xxx, server: DOMAIN.com, request: "GET /jenkins HTTP/1.1", host$

РЕДАКТИРОВАТЬ: друг получил это, отредактировав мой блок сервера ниже директив SSL, как это, но он пытался все, что работает, не уверен, что это лучший способ?
