      Forklift console plugin fails to load on IPv6-only OpenShift clusters::
         
      When {project-short} 2.9.1 is deployed on an IPv6-only OpenShift cluster, an incorrect API endpoint prevents the forklift-console-plugin from serving a valid plugin manifest, displaying the error "Failed to get a valid plugin manifest from /api/plugins/forklift-console-plugins/". While the forklift-ui-plugin pod runs successfully, the console plugin cannot load, preventing access to the {project-short} user interface in the OpenShift web console. This issue affects all IPv6-only cluster deployments with OpenShift 4.19.7 and CNV 4.19.1.
      +
      *Workaround:* None. Deploy {project-short} on dual-stack or IPv4 clusters until this issue is resolved.
