AWS AMI - Instance running, but now what?

I have read intro post: About the Installation Issues category
I have read the tutorials, help and searched for similar issues
I provide relevant information about my server (component names and versions, etc.)
I provide a copy of my logs and healthcheck
I describe the steps I have taken to trouble shoot the problem
I describe the steps on how to reproduce the issue

I read the guide here Passbolt Help | Using Passbolt PRO AWS AMI and subscribed to the AMI and selected the VPC, subnet etc and launched an instance.

The instance is running, but now what? The guide simply states, for step 2, “Before you can use the application, you need to configure it. Point your browser to the hostname / ip where passbolt can be reached. You will reach a getting started page.” but this is not the case.

I have clicked the public IP address in the instance details, and I get an “Unable to connect” page.

OK, seems like the issue is the documentation.

Step 1.1 is marked as optional but highly recommended. It should state that running sudo dpkg-reconfigure passbolt-pro-server via SSH is required.
