metric server 401 error

Hi, first of all is awesome the work done here. I'm trying to connect to the metric server using the link from the outcome of "kubectl cluster-info", I'm getting a 401, I can see working kubectl top node and top pod though, how can I configured properly permissions to access to the webui ? 

- using:
k3d version v4.4.6
k3s version v1.21.1-k3s1 (default)


thanks in advance,
Julio
