There is one pod of metal3 operator in constant failure state. The cluster was acting as Hub cluster with ACM + GitOps for SNO installation. It was working well for a few days, until this moment when no other sites could be deployed.

OCP version: 4.16.ec5
    

Once it starts to fail, it does not recover.
    

    1. Unclear. Install Hub cluster with ACM+GitOps
    2. (Perhaps: Update AgentServiceConfig
    

Pod crashing and installation of spoke cluster fails
    

Pod running and installation of spoke cluster succeds.
