AKS Cluster Creation in waiting state

Hi, I am trying to create AKS cluster from Rancher portal. AKS cluster created successfully from Rancher portal but in Rancher → Cluster Management page the “Status” of cluster showing as “waiting” with below error:

"Failed to communicate with cluster: error generating service account token: Post “https://:443/api/v1/namespaces”: dial tcp : i/o timeout

Please suggest how to resolve this issue.
