1322	"nginx: [emerg] open() ""/var/run/nginx.pid"" failed (13: Permission denied)"	beerich@…		"The error (in Summary) has showed up in fresh installs of both FreeBSD 11.0-RELEASE and 11.1-RC1.  Reinstalled nginx a number of times, with no changes in the result.  It's requiring Passenger, which isn't used because this error delivers a 404 before Passenger can provide a route.

Clean installation.  Passenger cannot provide a route, so the whole server delivers a 404.  Error reported:

nginx -t
nginx: the configuration file /usr/local/etc/nginx/nginx.conf syntax is ok
nginx: [emerg] open() ""/var/run/nginx.pid"" failed (13: Permission denied)
nginx: configuration file /usr/local/etc/nginx/nginx.conf test failed

Permissions on /var/run/nginx.pid are 640.  Same error with 655.  

Same problem happened on FreeBSD 11.0-RELEASE
