Unable to remove kubernetes worker node from rancher cluster UI

kubernete node has Ubuntu OS version 20.4.5
Rancher user interface version 2.6.3

Issue description:- Newly build node was stuck in registirig state (only eth0 IP was visible instead of both interface IP eth0 and eth1) while adding into the cluster.
we have tried rebooting node but it didnt help. So we tried remove it from Rancher UI but again it stuck with error “Waiting to register with Kubernetes; waiting on node-controller”.
Same node doesn’t exist when check from CLI mode (kubectl get node | grep -i )

We would require expert advice on step to remove node from rancher UI !!
