Nginx config file for this site didn't have gzip compression enabled. I copied the default file from here Nginx Recipes, updated server_name, and site path, and never bothered to check if compression is enabled or not.
This site is powered by Drupal 8. I'm using Nginx as a web server and Let's Encrypt to add HTTPS encryption to my site. In this post, I will show you how my Nginx config file looks like.
