Доброго времени суток.
Использовал связку nginx+unicorn, было все нормально. Решил попробовать nginx+passenger и внезапно появился странный баг.
Основную страницу и ресурсы (HTML, CSS, JS) сервер отдает нормально. Но если запросить через AJAX любой JSON-контент (типа /notes.json), то сервер ругается ошибкой «502 Bad Gateway». При этом если зайти браузером напрямую на тот же /notes.json, то данный отдаются нормально и статус «304 Not Modified». С Unicorn такого не было, появилось именно с Passenger.
Конфиг практически стандартный, брался
отсюда.
Никто случайно не подскажет, что это за нафиг может быть?
Конфиг nginx:
user www-data;
worker_processes 4;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {
sendfile on;
tcp_nopush on;

passenger_root /usr/local/lib/ruby/gems/2.0.0/gems/passenger-4.0.5;
passenger_ruby /usr/local/bin/ruby;
server {
server_name notes-test.com;
listen 80;
root /srv/notes-test.com/public;
passenger_enabled on;
rails_env development;
}
}
В логах у nginx вот такие ошибки:
