I followed the DNS quickstart guide (https://www.digitalocean.com/docs/networking/dns/quickstart/) and afterwards the nginx guide (https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-18-04)

At my registrar I set my domain (my-stuff.io) to point at DO nameservers. I can see they are in fact pointing to those servers when I do a whois.

Are there any common pitfalls I could’ve fallen into following those guides? I am not really sure where the error occurs, because I just get server not found when going to my-stuff.io.
