Hi, I am beginner user of RKE2. For learning purpose, I would like to setup 3 EC2 node RKE2 cluster, with Nginx LB inside its own EC2 machine in front. Can somebody help me with the setup of nginx.conf? There is example how to setup this, on Rancher Docs, but example uses ports 80 and 443, I guess for RKE2 I need 9345 and 6443 ? I have tried simply adapting the config with these 2 ports for RKE2, but when I launch 2 server node, it fails with no being able to connect to DNS_name:9443/cacerts. Does something need to be setup in config.yaml to use Load balancer ?
