Cattle-cluster-agent "certificate signed by unknown authority"

Hi I have installed the root ca’s on my machine and I did set the full-chain to the rancher’s ingress,
But I keep getting the same errors when I try to import new rke2 cluster:

It’s not a certificate issue,
is there any way to pass this?

You need to check your certificate . It must’ve wrong CA. You should not import any CA to vm.
