Hi
I'm a new on nginx configuration, I've tried today to up load balancer for my elasticsearch service instances
I don't know what's wrong?
"/docker-entrypoint.sh: Configuration complete; ready for start up
2022/03/14 17:46:54 [emerg] 1#1: "server" directive is not allowed here in /etc/nginx/nginx.conf:42
nginx: [emerg] "server" directive is not allowed here in /etc/nginx/nginx.conf:42
"
