Rancher gives this error when trying to do anything from Cluster Management

Internal error occurred: failed calling webhook "<http://rancherauth.cattle.io|rancherauth.cattle.io>": failed to call webhook: Post "<https://rancher-webhook.cattle-system.svc:443/v1/webhook/validation?timeout=10s>": no endpoints available for service "rancher-webhook"

The rancher-webhook is present. It is possible that the certificate has expired so delete the secret and restart (kill) the rancher webhook pod

I solved the issue by stopping the pod and starting it with a different version of the rancher image. It seemed the specific version (i cannot remember which) had issues
