Rancher cluster - How to login to the dashboard?

1

I installed a stable rancher cluster following these instructions

I chose the last type of installation (Certificates from Files)

Now how can I view the rancher login page?

I tried to connect to url:
https://rancher.my.org:6443/
but i see this error:

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {
    
  },
  "status": "Failure",
  "message": "Unauthorized",
  "reason": "Unauthorized",
  "code": 401
}
