Unable to connect to DigitalOcean Droplet

I followed the DigitalOcean installation instructions but when I try to connect to the server Safari says it could not connect to the server. I can neither browse directly to the ip adress. However the server seem to exist in digital ocean and I can open a terminal too it from their admin page.

Where should I start troubleshooting?

If it matters I have not signed up for a plan yet. Want to see that the installation works first.

Figured it out. The manual does not show how to set LETSENCRYPT_DOMAIN that is needed.

Thanks for pointing out that omission in the docs. It's been corrected now.
