Remove Existing Nginx Configuration: sudo rm -rf /etc/nginx/nginx.conf

Edit New Configuration: Use a text editor like nano to create a new configuration file.

sudo nano /etc/nginx/nginx.conf

• Replace the contents with your load balancer configuration. You can use the Example Nginx config as a starting point.

• Modify RPC/LCD/gRPC server entries and domain names as required.

sudo nginx -t

sudo systemctl enable nginx && sudo systemctl start nginx

crontab -e

Then, add:

0 12 * * * /usr/bin/certbot renew --quiet
