on control nodes, the following added in /etc/rancher/rke2/config.yaml
…
disable-cloud-controller: true
cloud-provider-name: external

The above config works on another cluster. but failed on this one.

ok. the issue resolved. credential issue. I had to put username in a certain format to make it work. A different format works for another cluster but not this one.
