I agree with @ben
Given that I had most of this typed, I’ll still send it along…
If you’re saying you’ve run server.yml and deploy.yml then you point your web browser at your IP and get an empty response, I speculate that it is because your Nginx isn’t configured to process requests to the IP name, only the domain name. Here are the site_hosts for which your server will process requests. By default, this doesn’t include the IP.
Ultimately, you’ll want to connect using a fqdn once you have DNS set up. If that is not yet set up, I’d recommend making an entry in your local machine’s /etc/hosts
146.185.132.84 mydomain.com
then point your browser at mydomain.com instead of the IP.
Maybe it would work to add the IP to the site_hosts list (but I vaguely remember that may have other issues with css/js relative paths not resolving).
