Read v2rayN logs by following the traffic path

Useful diagnosis finds the first real error around a known timestamp, rather than publishing an entire log dump.

Steps

  1. Reproduce the smallest failure once and note the exact time. Clear old logs first when possible.
  2. Confirm core version, config path and listening ports, then search for error, failed, timeout and refused.
  3. Follow the request through inbound, DNS, matched route and outbound to find the first missing stage.
  4. Before sharing, replace server names, UUIDs, subscription URLs, usernames and local paths while preserving timing and error types.

Why this matters

The final error may be a downstream symptom. Reading in data-flow order identifies whether startup, DNS, routing or outbound failed first.

How to verify

You can state the failed layer in one sentence and confirm it with one isolated configuration change.

Things to watch

Do not leave debug logging enabled permanently. It increases disk writes and can retain more browsing metadata.
