Hi,

I am encountering an issue with Linkerd-viz after performing a fresh installation on an EKS cluster.

When I execute the command:  
$ kubectl get [apiservices.apiregistration.k8s.io](http://apiservices.apiregistration.k8s.io) [v1alpha1.tap.linkerd.io](http://v1alpha1.tap.linkerd.io)

the output shows that the tap service is not available:

NAME SERVICE AVAILABLE AGE  
[v1alpha1.tap.linkerd.io](http://v1alpha1.tap.linkerd.io) linkerd-viz/tap False (FailedDiscoveryCheck) 158m

It appears that the tap service is unreachable from the control plane, or there could be another underlying issue causing this problem. I am unsure what could be causing this issue. Can anyone help me troubleshoot?

Thank you!

Hi @gabriel! I see that you posted on [slack.linkerd.io](http://slack.linkerd.io):

> Was solved adding ports 8088/8089 to nodes security group…

Is everything working as intended now?
