Hey, This is my first post on this forum. I do not speak good English but I will try to write clearly.
I have problem with Nginx + php-fpm and fast cgi connection time out.

My error log

2016/01/01 22:58:58 [error] 2367#0: *13 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 10.10.12.101, server: xxx.org.pl, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xxx.org.pl", referrer: "http://xxx.org.pl/"
