I used https://docs.microsoft.com/en-us/azure/aks/certificate-rotation this link to rotate certificates in AKS. Certificate got updated but my cluster is in failed state. Because of this my application is down.

I am getting below mentioned error when I am running this command az aks rotate-certs -g $RESOURCE_GROUP_NAME -n $CLUSTER_NAME

ERROR: "error": { "code": "ErrorCodeRotateClusterCertificates", "message": "VMASAgentPoolReconciler retry failed: Category: ClientError; SubCode: OutboundConnFailVMExtensionError; Dependency: Microsoft.Compute/virtualMachines/extensions; OrginalError: Code=\"VMExtensionProvisioningError\" Message=\"VM has reported a failure when processing extension 'cse-agent-0'.
