After pointing www.shop.example.com at the cluster, shop.example.com works but the www address gets nginx's 404. `kubectl get ingress shop` lists only HOSTS shop.example.com.

같이 보면 좋은 질문
Should I translate commands, logs, or product names?

No. Keep commands, logs, file names, APIs, and product names unchanged, then explain the reasoning in the selected UI language.

What should the answer focus on?

State the root cause, the evidence that supports it, and the safest recovery direction.

Why can the scenario remain in the original language?

The source scenario is treated as an incident artifact. Guidance, checklist, hints, and explanations can be localized around it.
