Error message after removing shutdown node from Rancher2 Cluster

Hi, I have a Rancher2.0 k8s cluster (on premise) running and I had drained and shut down one of my 6 nodes.
I then deleted this node from Rancher (I realise now I should’ve deleted it from Rancher before shutting it down).

The node6 no longer shows in the list of nodes but the following error has been cycling for at least an hour:

This cluster is currently Updating .

Failed to delete controlplane node [] from cluster: Get can not build dialer to c-hkgb9:m-2bfec108efe4

I have started the machine back up in the hope that Rancher will perform the cleanup but am unable to get the error to stop.
