Hi all, I've got a k8s cluster deployed through rancher and every now and then we get the following error:

Error from server (InternalError): Internal error occurred: failed calling webhook "<http://rancher.cattle.io|rancher.cattle.io>.namespaces.create-non-kubesystem": failed to call webhook: Post "<https://rancher-webhook.cattle-system.svc:443/v1/webhook/validation/namespaces?timeout=10s>": context deadline exceeded

We aren't really sure whats going on here. We've updated our rancher container, checked firewall rules, but nothing. The only "solution" is to do the following:

kubectl delete mutatingwebhookconfigurations <http://rancher.cattle.io|rancher.cattle.io>
kubectl delete validatingwebhookconfigurations <http://rancher.cattle.io|rancher.cattle.io>
kubectl -n cattle-system delete service rancher-webhook
perform a fake upgrade to the rancher-webhook installed app in rancher gui

Am I just hitting a really unlucky bug? It seems to be something to do with the rancher webhook service, but I cannot pinpoint it at all. These are physical nodes with the exception of the controlplane/etcd nodes which are vms
