Unable to setup Rancher 2.6

Hello,

I’m trying to install Rancher on a kubernetes cluster configured through RKE but facing issues.
I’m done with the cert-manager step and used below command to install Rancher:

helm install rancher rancher-latest/rancher --namespace cattle-system --set hostname=rancher.167.xx.xx.181.sslip.io --set replicas=1

All the pods under cattle-system ns are going into Error state.

Pods have two containers running ‘helm’ and ‘proxy’ out of which container ‘helm’ is failing for all pods.

[kubenode@localhost ~]$ kubectl logs helm-operation-9pvn9 helm -n cattle-system
