A follow-up should move the discussion forward without pretending you have full context. Begin with what you tried, what actually happened, and what remains unknown. Link or briefly summarize the earlier advice you followed so readers do not have to reconstruct the thread.
For example: “I changed the timeout from 10 to 30 seconds. The request now completes locally, but the hosted version still fails. I have not checked its proxy settings.” That distinguishes a measured result from a possible cause. End with one focused question, such as which log or setting to inspect next. Correct earlier assumptions openly if new evidence contradicts them.
