+= Refreshing failing subscriptions
+
+In Operator Lifecycle Manager (OLM), if you subscribe to an Operator that references images that are not accessible on your network, you can find jobs in the `openshift-marketplace` namespace that are failing with the following errors:
+
+.Example output
+[source,terminal]
+----
+ImagePullBackOff for
+Back-off pulling image "example.com/openshift4/ose-elasticsearch-operator-bundle@sha256:6d2587129c846ec28d384540322b40b05833e7e00b25cca584e004af9a1d292e"
+----
+
+.Example output
+[source,terminal]
+----
+rpc error: code = Unknown desc = error pinging docker registry example.com: Get "https://example.com/v2/": dial tcp: lookup example.com on 10.0.0.1:53: no such host
+----
+
+As a result, the subscription is stuck in this failing state and the Operator is unable to install or upgrade.
+
+You can refresh a failing subscription by deleting the subscription, cluster service version (CSV), and other related objects. After recreating the subscription, OLM then reinstalls the correct version of the Operator.
+
+.Prerequisites
+
+* You have a failing subscription that is unable to pull an inaccessible bundle image.
+* You have confirmed that the correct bundle image is accessible.
+
+.Procedure
+
+. Get the names of the `Subscription` and `ClusterServiceVersion` objects from the namespace where the Operator is installed:
++
+[source,terminal]
+----
+$ oc get sub,csv -n <namespace>
+----
++
+.Example output
+[source,terminal]

+. Delete the cluster service version:
++

+----

+. Get the names of any failing jobs and related config maps in the `openshift-marketplace` namespace:

+----
+
+. Delete the job:
++
+[source,terminal]
+----
+$ oc delete job <job_name> -n openshift-marketplace
+----
++
+This ensures pods that try to pull the inaccessible image are not recreated.
+
+. Delete the config map:
++
+[source,terminal]
+----
+$ oc delete configmap <configmap_name> -n openshift-marketplace
+----
+
+. Reinstall the Operator using OperatorHub in the web console.
+
+.Verification
+
+* Check that the Operator has been reinstalled successfully:

+[source,terminal]

+$ oc get sub,csv,installplan -n <namespace>
