Why doesn't my cluster add-on work?

When you try to use a cluster add-on in IBM Cloud Satellite®, the cluster add-on does not work. For example, you installed the Kubernetes web terminal add-on but cannot open the add-on.

Add-ons might not work for several reason.

The add-on is not supported for clusters in a Satellite location.
The add-on is in an unhealthy state.
The add-on settings are misconfigured, such as renaming or editing a ConfigMap.
The add-on cannot be backed up in IBM Cloud Object Storage due to conflicting service instance and bucket endpoints.

Take the following steps to troubleshoot the add-on.

Check that the add-on is supported. If not, uninstall the add-on.
If the add-on is misconfigured, refresh the cluster master to restore the add-on to the default settings.
```
ibmcloud oc cluster master refresh -c <cluster_name_or_ID>
```
If the add-on is in critical state, review the IBM Cloud Object Storage instance and bucket that backs up the cluster data. The instance and endpoint must have matching endpoints, such as a Global instance with a Cross Region bucket (us-geo endpoint), or a Regional instance with a Regional bucket (us-east endpoint). If the endpoints do not match, you must re-create the Satellite location with matching IBM Cloud Object Storage instance and bucket endpoints.
For more information, review the add-on state and statuses.
