After installing OCP 4.14/4.15 on OpenStack using installer, the network operator is stuck in forever updating with the following warnings:

KubeDeploymentReplicasMismatch
Deployment openshift-cloud-network-config-controller/cloud-network-config-controller has not matched the expected number of replicas for longer than 15 minutes. This indicates that cluster infrastructure is unable to start or restart the necessary components. This most often occurs when one or more nodes are down or partioned from the cluster, or a fault occurs on the node that prevents the workload from starting. In rare cases this may indicate a new version of a cluster component cannot start due to a bug or configuration error. Assess the pods for this deployment to verify they are running on healthy nodes and then contact support.

KubePodCrashLooping
Pod openshift-cloud-network-config-controller/cloud-network-config-controller-5ffd6646c-wh5pk (controller) is in waiting state (reason: "CrashLoopBackOff").
    

Any 4.14, 4.15
    

Always
    

    1. Install OCP on OpenStack using the installer, we use the following config that worked with OCP 4.13 and before with no issues:
