After following the guide on [linkerd.com](http://linkerd.com) to install it on my K3sup Cluster server, I have run into a few problems. Bear with me if this is an easy fix, I am still learning how clusters work and Linkerd.

My environment is Ubuntu Server LTS 20.04.2 on a Raspberry Pi4 which has K3sup installed. I have set up the nodes properly and when I pull my nodes in the terminal, this is what it shows.

```
    NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME

```

Running through `linkerd check --pre --linkerd-namespace linkerd-test` I have also discovered this problem

```auto

    see https://linkerd.io/checks/#pre-k8s-cluster-k8s for hints

When I run `linkerd viz dashboard &`

```auto
http://localhost:50750
Grafana dashboard available at:
http://localhost:50750/grafana
Opening Linkerd dashboard in the default browser
Failed to open Linkerd dashboard automatically

```

When I open the link on my machine, the site cannot be reached. What is the solution to this problem? Thank you.
