Scenario
Issuance breaks only after a hardened runtime class rollout.
A cert-manager DNS01 challenge loops because the solver runtime class blocks the projected token path the cloud helper expects
The challenge is correct, but the hardened runtime hides the token path used by the helper.
What to check first
- Identify the primary failure signal in the The Hardened Runtime Hid the One Token Path the Solver Needed scenario.
- Separate visible symptoms from the underlying technical dependency.
- Describe the safest recovery path and the follow-up prevention work.
Checking checklist
- Summarize the current impact and the last known change.
- Collect direct evidence from logs, runtime state, and configuration before changing anything.
- Separate immediate recovery from permanent prevention work.
Recovery and prevention
Inspect token projection paths before changing DNS credentials.
Questions worth viewing together
No. Keep commands, logs, file names, APIs, and product names unchanged, then explain the reasoning in the selected UI language.
State the root cause, the evidence that supports it, and the safest recovery direction.
The source scenario is treated as an incident artifact. Guidance, checklist, hints, and explanations can be localized around it.
