Hello, is it normal after manual startup? If it is normal, I suggest you check whether it has been shut down by the system?
You can use Cron to add a shell script to automatically start nginx when nginx stops
NGINX_STATUS=$(curl -s --connect-timeout 10 -m 10 2>/dev/null -w "%{http_code}" 127.0.0.1 -o /dev/null)
if [ "${NGINX_STATUS}" != "200" ];then
/etc/init.d/nginx restart
