K8s heapster gets response 307 from all kubelets

Rancher 1.x

Hi,

I am not being able to get the metrics of my k8s cluster. When I look at the logs from the heapster I got this:

I have already tried to restart all the kubelets and the heapster, but I still got the same error.

I am using rancher V1.6.10
