Hey Ranjith,

Thanks for the reply and suggestion. I make the suggested changes in nginx.conf on my nginx-lb

upstream backend {
   server 192.168.1.41:32606;
   server 192.168.1.42:32606;
}
# This server accepts all traffic to port 80 and passes it to the upstream.
server {
   listen 80;
   location / {
      proxy_pass http://backend;
   }
}

Now when i try to access my web page via load balancer ip , i am getting bad gateway error on the browser and i am also getting following errors in error log file on nginx-lb

   [root@lb1 ~]# tailf /var/log/nginx/error.log
