I get 504 gateway timeout when I try to reach my server.
A small check didn't find any logs on php5-fpm logs, but just to make sure, I tried to restart it.
When I am trying to restart it:
sudo service php5-fpm restart
[fail], but when I do
sudo service php5-fpm stop sudo service php5-fpm start
I get no error.
How can I investigate it if there are no logs? What can I do?
