Nginx 504 Time-out with php-fpm - nginx

Question

I got 504 Gateway Time-out for one of my sites. Please, help to find out why?
Here's my nginx configuration:
server {
listen 80;
server_name domain.com;
root /home/user/domain.com;
error_log /home/user/domain.com/error.log;
location / {
try_files $uri /index.php?q=$uri&$args;
}
location ~ \.php$ {
include fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
Nginx error log:
$ sudo tail -n 1 domain.com/error.log
2014/08/21 17:09:35 [error] 16790#0: *30 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 5.18.54.52, server: domain.com, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock", host: "domain.com"
And nothing in php-fpm log:
sudo tail -n 1 /var/log/php5-fpm.log
[21-Aug-2014 17:08:31] NOTICE: ready to handle connections
And here my www.conf:
$ sudo nano /etc/php5/fpm/pool.d/www.conf
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 1
pm.max_spare_servers = 10
Please help me to solve this! Thanks!

As of PHP 5.5.12 FPM Socket permissions were changed to resolve a security related bug, you can read more about that here -> https://bugs.php.net/bug.php?id=67060
Your listen.mode = 0660 should now be set to listen.mode = 0666 inside of your FPM Pool Configuration. Also make certain that your listen.owner and listen.group is the same user name/group that is running Nginx. Here is what I have in my setup:
listen.owner = nginx
listen.group = nginx
listen.mode = 0666
I am assuming that your Nginx Configuration has user www-data; then simply change the nginx reference I have above to www-data of course.
As for Nginx here is a working example I am currently using:
# PHP-FPM Support
location ~ \.php$ {
fastcgi_pass unix:/var/run/nginx.sock;
include fastcgi.conf;
}
I think your Nginx Configuration is just fine, but in case you wanted to try something a little different I'm posting my config as a test for you.
Don't forget to restart PHP-FPM after making any configuration changes too.
Give this a try, I'm certain it should resolve your problem.
