When a ROSA classic cluster is hibernated and later resumed, the route API is not available immediately. When I check the status of the ingress cluster operator, it is reporting an error and becomes available after a considerable delay. GitOps operator depends on the availability of the route API to extract the host name of the service. Since the API is not immediately available, the operator assumes that the cluster does not support route API and initializes a wrong URL. The operator also fails to reconcile the Route that was created by it prior to the hibernation process.

Always
    

    0. Ensure that you have ROSA (Classic) cluster with hibernate/resume capability enabled.
    1.  Hibernate the cluster using the following command 
ocm hibernate cluster <cluster name or UUID>
    2.  After a while, when the cluster is successfully hibernated, resume the cluster using the following command.
ocm resume cluster <cluster name or UUID>
    3.  Check for the availability of ingress cluster operator post resume using the below command
oc get co ingress
    4.  Check for the available APIs using the below command
oc api-versions
    

> oc get co ingress
ingress                                    4.14.0    False       True          False      21s     The "default" ingress controller reports Available=False: IngressControllerUnavailable: One or more status conditions indicate unavailable: DeploymentAvailable=False (DeploymentUnavailable: The deployment has Available status condition set to False (reason: MinimumReplicasUnavailable) with message: Deployment does not have minimum availability.)

    1. Ingress cluster operator should become available without any errors or delays.
    2. oc api-versions command should have Route API listed under route.openshift.io/v1 group.
