Same issue was spotted both on 4.9 and 4.10 latest builds (with kata 1.1.0)


How reproducible:
Deploy kata operator in disconnected environment
Create kataconfig just after pods are running in openshift-sandboxed-containers-operator namespace

Actual results:
Post \"https://sandboxed-containers-operator-controller-manager-service.openshift-sandboxed-containers-operator.svc:443/validate-kataconfiguration-openshift-io-v1-kataconfig?timeout=10s\": dial tcp 10.130.0.55:9443: connect: connection refused"

Expected results:
Post should succeed and kataconfig applied

Additional info:
Looks like timing issue, fails sporadically in CI
