Why getting 404 on EKS

I have followed all the instructions to install rancher on an AWS EKS cluster as given here.

Installing Rancher on Amazon EKS

I installed my TLS certificate, everything completed as expected, but when I try connect to the external ip provided by this command:

kubectl get service ingress-nginx-controller --namespace=ingress-nginx

…all I get is 404 not found. Everything seems to be running properly but the Rancher server does not respond. Any clues?
