This is what i get when i submit the task: - ‘nginx’ on LBR Server is not configured to use all app servers

This is my work:
thor@jumphost ~$ ssh tony@stapp01

ED25519 key fingerprint is SHA256:VsZLOQcahVkli230sk8xK5CtYFNvts90/Kbiacl90jA.

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

tony@stapp01’s password:

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

HI @Slicky

It would have helped if you had shared the nginx.conf you have configured on the LoadBalancer server in a code block.

Hi Santosh, this is my stlb01 config:

user nginx;
worker_processes auto;

events {
worker_connections 1024;
}

http {
# Upstream load-balancer pool
upstream app_backend {
server stapp01:6400;
server stapp02:6400;
server stapp03:6400;
}

sendfile on;
keepalive_timeout 65;

server {
    listen 80;
    server_name stlb01;

    location / {
        proxy_pass http://app_backend;

        # Standard proxy headers
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

}
