[HELP] aws chefautomate delivery token auth failure

I am following the guide here: https://learn.chef.io/modules/deploy-infrastructure/ubuntu/opsworks/set-up-your-workstation#/

There are a couple of bits that an issue for me, at this time. First, unable to add an SSH key as designated in the instructions, and I have not done this, as interface is different as compared to instructions. Right now I am using an ssh-agent from my workstation to a AWS jumpbox and then use this to connect to my automate instance I've deployed in AWS.

The issue I am having is that I can't generate a delivery token:

ubuntu@ip-address:~/learn-chef$ AUTOMATE_PASSWORD=PASSWORD delivery token
Chef Delivery
Requesting Token
401: Authentication failed
token request returned 404 Not Found

Any ideas on how to resolve this issue?
