ruby on rails - Do I need to restart NginX after reconfigure for passenger to work -

i updated nginx configuration. in config i've added new server different environment rails application.

i've reloaded configuration (sbin/nginx -s reload) , deployed application right folder nothing seems happen, nginx throws 404 not found..

is there more need do?

do need restart nginx or passenger example?

turns out don't need restart.

passenger isn't able restart (as far i've found out) , nginx needs reload.
