AWS EKS Guestbook url not accessible

Question

I'm on Win10 using cygwin and some other choco stuff, everything is installed and runs fine. I was able to install and run stuff from ecs-cli and fargate tutorial and compose too.

Now I'm trying EKS and set up cluster and guest book from the Getting Started with ekstcl here: https://docs.aws.amazon.com/eks/latest/userguide/getting-started-eksctl.html

And then after cluster is set up here: https://docs.aws.amazon.com/eks/latest/userguide/eks-guestbook.html

I created AWS Fargate-only Cluster. I'm just following step by step by and in the end when I'm opening the url in the browser it says

This page isn’t working
a8b3bb2e121f511ea82cb1294ea943ee-1408939369.us-east-1.elb.amazonaws.com didn’t send any data.

And get nothing :(

What am I doing wrong?

You're not doing anything wrong. However, when using EKS on Fargate you have to consider certain things. This includes, as of time of writing, that only ALB is supported. The Guestbook example uses a service type LoadBalancer, causing the creation of a classic load balancer, which is, ATM, not supported in EKS on Fargate.
