Beginner noob question

I am trying to do this tutorial Get started with Kubernetes (using Python) | Kubernetes on my local machine (mac osx)

I have accomplished all of the steps:

app git:(master) ✗  kubectl get pods

NAME                            READY   STATUS    RESTARTS   AGE
hello-python-6c7b478cf5-49vdg   1/1     Running   0          2m53s
hello-python-6c7b478cf5-d4tfl   1/1     Running   0          2m53s
hello-python-6c7b478cf5-ltb8r   1/1     Running   0          2m53s
hello-python-6c7b478cf5-qsqvt   1/1     Running   0          2m53s
 app git:(master) ✗

But when I go to localhost:6000 I get an error:

This site can’t be reached. The web page at http://localhost:6000/ might be temporarily down or it may have moved permanently to a new web address.
ERR_UNSAFE_PORT

When I do lsof -i tcp:6000 I get this:


COMMAND     PID        USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
com.docke 98546     <me>   76u  IPv6 0xc52e947a7a450f69      0t0  TCP *:6000 (LISTEN)

Is this a bug in the tutorial, or am I doing something wrong?

I am a complete beginner - please let know what information I need to provide that might be helpful to debug this.

Google expression:
(…)
ERR_UNSAFE_PORT
(…)
It could be a browswer thing. Did you try : curl http://localhost:6000 ?
