OpenShift 4.5 and forward uses the api priority and fairness feature to limit the rate at which the API server accepts requests. Run the following command: #Verify the APIPriorityAndFairness feature-gate oc get kubeapiservers.operator.openshift.io cluster -o json | jq '.spec.observedConfig.apiServerArguments' For 4.5, verify that the feature-gate is turned on for the APIServer priority and fairness: APIPriorityAndFairness=true. In OCP 4.5 and earlier, the default set of admission plugins are compiled into the apiserver and are not visible in the configuration yaml.

How it is fixed
