21.1.8 - nginx doesn't start

[GreenMatter]

After upgrading to 21.1.8 and reboot, nginx can't be run. When I try to do it manually I get:

root@OPNsense:~ # service nginx start
Performing sanity check on nginx configuration:
nginx: the configuration file /usr/local/etc/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/etc/nginx/nginx.conf test is successful
Starting nginx.
nginx: [emerg] bind() to unix:/var/run/nginx_status.sock failed (48: Address already in use)
nginx: [emerg] bind() to unix:/var/run/nginx_status.sock failed (48: Address already in use)
nginx: [emerg] bind() to unix:/var/run/nginx_status.sock failed (48: Address already in use)
nginx: [emerg] bind() to unix:/var/run/nginx_status.sock failed (48: Address already in use)
nginx: [emerg] bind() to unix:/var/run/nginx_status.sock failed (48: Address already in use)
nginx: [emerg] still could not bind()
/usr/local/etc/rc.d/nginx: WARNING: failed to start nginx

It must be related to update since I had changed nothing in nginx setup...
sockstat output doesn't show "/var/run/nginx_status.sock", socket doesn't exist???

EDIT:
Strange enough, after additional, post-update reboot nginx is up and running...

There was likely an old process so the socket was not free. However you could have just deleted the socket file as well and restarted nginx afterwards.
