New RKE cluster rancher/metrics-server:v0.3.6 - HTTP probe failed with statuscode: 404


We’ve just built our first cluster using RKE version v1.2.6. All is well apart from the rancher/metrics-server pod, which I’d like to get working. I’m not sure where to start and any help would be much appreciated. I noticed the --kubelet-insecure-tls flag is set already, so it’s probably not a certificate issue.

See some screenshots from the dashboard below (I can only embed one as new to this forum, so I’ve included the one I think it most useful).

The only line in the logs says:

I0316 08:53:46.747611       1 secure_serving.go:116] Serving securely on [::]:4443

Thanks in advance for any help.
