Before suggesting a fix, tell me in one sentence what you think the
root cause is. If you are guessing, say so and tell me what to check
or log to confirm it.

Never open with "it doesn't work". Models will happily invent a plausible cause for a symptom you haven't described, and you'll spend the next twenty minutes disproving it.
