Hello, I get a huge issue in the company right now. I have a rancher cluster v1.13.5 with 3 Pools where 2 pools with works and 1 to etcd and control plane.
The pool for etcd have 1 node that server for etcd and control plane. My Issue: the public IP from this server was changed and now I have the server with 1 IP and in rancher with old IP and after that my Cluster got stuck in the status Updating.
This action don’t affected my works but I can do anything in the cluster only I can have access to rancher UI. I have tried to add a new Node through the Rancher Console which I can see the new server but the server stay in the Waiting for Registration and never get Activated.
When I check the Rancher console I can see the etcd1 - unhealthy which is probably the because of the wrong IP in the etcd.
Any idea how I can fixed all this mess?
