   > firewall-cmd --reload
   

5. Comment out the existing server information details in the /etc/nginx/nginx.conf file as shown below.

6. Restart and enable nginx service:

   > systemctl enable nginx.service
   > systemctl restart nginx.service
   > systemctl status nginx.service
   

   NOTE

   NGINX service should be Active and running.

7. Navigate to the NGINX configured IP on browser and HPECP gateway page should come up:
