Nginx Node Frontend / Load Balancer / Static Assets Caching

gistfile1.js

upstream project {
  server 22.22.22.2:3000;
  server 22.22.22.3:3000;
  server 22.22.22.5:3000;
}

server {
  listen 80;

  location / {
    proxy_pass http://project;
  }
  location ~* \.(css|js|gif|jpe?g|png)$ {
    expires 168h;
    
  }
  location /api {
    expires 10m;
  }
}

Why doesn't nginx load balance to my box with an express app running ?

ngnix is running on box1 under 55.55.55.5
express app is running on box2 uder 55.55.55.2:3000

When I'm going to 55.55.55.5 I'm getting this - Welcome to nginx! bla bla bla

upstream project {
  server 55.55.55.2:3000
}

server {
  listen 80;

  location / {
    proxy_pass http://project;
  }
}

SOLVED

The issue was because of default conf file in sites-available, just delete or rename it and you good to go.

if something is wrong try like this

location ~ ^/views/((css|js|gif|jpe?g|png).*)$ {
expires 168h;

}

can you please write this code in apache also.
