Airflow Deployment permission denied

Testing out Astronomer on EKS. Pretty new to this, so please bare with me.
Using this guide https://docs.aws.amazon.com/eks/latest/userguide/getting-started-console.html, I created a new EKS deployment from the AWS Management Console, using Public/Private Subnets and Managed Nodes - Linux.
Then I created the Astronomer deployment from here https://www.astronomer.io/docs/ee-installation-eks/. I included the line postgresqlEnabled: true. I successfully got Astronomer installed.

I am able to login to the Astronomer UI as the System Admin and create a Workspace and an Airflow deployment. Once the Airflow deployment completes, and I click on the Open Airflow button I get a page that says

Uh oh!

You do not have permission to view that page

Open Celery shows one worker with Status: True and everything else with a 0.

I tried using astro deployment create new-deployment-name123 --executor=celery --cloud-role={arn-role} and using the eksClusterRole IAM role. Again the deployment appears to build, but denies access.

The Scheduler and Webserver logs both show Waiting for host: explosive-terrestrial-0779-pgbouncer.astronomer-explosive-terrestrial-0779.svc.cluster.local 6543

Any ideas on what I did wrong?
