HI

I§m trying to create a 3 node server plan cluster with X number of RKE workder nodes.

I have followed this process with terraform.

a) Provisioned LB and EC2 instances with RHEL  
b) Created 1 server node with rancher 2.7. on is  
c) Added the 2 workder nodes to the new cluster.

This is on AWS.  
Now I want to add additional server nodes to the control plane (group)

So I provisoned some more EC2 instance with RHEL on them. Server2 and Server3 lets say.  
Tehn I try to add them according to this note:

> **[High Availability | RKE2](https://docs.rke2.io/install/ha)**
>
> This section describes how to install a high availability (HA) RKE2 cluster. An HA RKE2 cluster consists of:

Just add server nodes.  
After provisioning, command should be …

curl -sfL [https://get.rke2.io](https://get.rke2.io/) | INSTALL\_RKE2\_CHANNEL=v1.24 sh -s - server --server=[https://\<\>:9345] --token \<\>

This is the same command we used for the agent, except we used type ‘agent’ for the 2 worker nodes.

Server2 wont even connect to Server 1 after the DNS… Both ports 9345 and 6443 are open.

Any thoughts?
