I have installed packages nginx-ssl and nginx-ssl-util. After installed nginx-ui. nginx will not start.

root@AP2-p1:# /etc/init.d/nginx start
nginx_init: NOT using conf file!
show config to be used by: nginx -T -c '/etc/nginx/nginx.conf'
root@AP2-p1:# nginx -T -c '/etc/nginx/nginx.conf'
2025/11/01 19:54:33 [emerg] 5282#0: unknown directive "stub_status" in /etc/nginx/conf.d/stub_status_nginx-ui.conf:9
nginx: configuration file /etc/nginx/nginx.conf test failed

Solved -- I was using openwrt nginx-ssl which did not have the stub-stats module, after installing nginx-full it worked without error.
