machine where you are installing discourse.

The first thing to do is confirm that [discourse.32questions.com](http://discourse.32questions.com/) resolves to the  IP address of this server.
You usually do this at the same place you purchased the domain.

If that is the correct ip for your droplet then the next possibility is that you somehow have some firewall configured.

Since I have never created an A record take this with a grain of salt.
