Serving an HTML website using a Digital Ocean droplet

I have followed this step by step guide from 2016 to set up my droplet and domain.

how can i simply start a HTML page and start my own page and i want to know how to edit it later Url: https://www.digitalocean.com/community/questions/how-can-i-simply-start-a-html-page-and-start-my-own-page-and-i-want-to-know-how-to-edit-it-later

Unfortunately, I cannot reach my website using the browser.

I have followed all the steps above and my domain (from GoDaddy) is pointing to my Digital Ocean droplet (Ubuntu 18.04.3 (LTS) x64). For the domain configuration, I have followed this explanation.

The only thing I have done different is this:

• I had to create this route /var/www/html manually though. It was not in the droplet when I accessed it.

I was wondering if I am missing anything and if the post above is still accurate after three years. Also, would you recommend anyway to troubleshoot this? Any help would be really appreciated.
