Description of problem:
Failed to load live state: 503 Service Unavailable when fetching OpenAPI resources via cluster-proxy-addon
Version-Release number of selected component (if applicable): 2.16
How reproducible: Always
Steps to Reproduce:
- In 2.16 fresh install env, create a GitopsCluster against managed clusters
- Check that the default secure cluster secrets via cluster proxy is generated in the openshift-gitops ns
- Create a Push Model Type Appset against a managed cluster (not the hub)
- Check the Argocd Application created by the Appset
Actual results:

Expected results:
The application should be Sync and Healthy
Additional info:
We noticed the managed cluster is the latest OCP 4.21. Not sure if cluster proxy agent has been verified on it
