# How do I collect VilaNet diagnostics?

Preserve the first useful error, reproduce the problem once, and collect the
support information available in your VilaNet app. Review everything before
sending it; never include a password or raw subscription data.

1. Note your device platform, VilaNet version, selected server and network type.
2. Record the exact error text and when the problem occurred.
3. Reproduce the problem once without repeatedly reinstalling or changing
   advanced settings.
4. Open the diagnostics or support area documented for your VilaNet platform.
5. Use its copy or export option only if one is present in your current app.
6. Review the information and remove passwords, raw subscription URLs, tokens,
   account details and unrelated private information.
7. Send the redacted information with a short description of what you expected
   and what happened.

## Success check

You have the exact error, platform, app version, selected server, network type
and redacted support information. The material is useful only after you have
reviewed it for private data.

## If diagnostics are unavailable

- **There is no diagnostics or export option:** do not guess a hidden path.
  Send the exact error and the context listed above instead.
- **The app closes or loses the error:** record what is still visible and stop
  changing settings before more evidence is lost.
- **You are unsure whether the export is safe to share:** do not send it. Follow
  [Contact support](/en/troubleshooting/contact-support/) with the non-sensitive
  details first.

> **Screenshot needed:** capture each platform's real diagnostics or support
> area and its copy/export flow, if present, with all customer, account, server
> and network identifiers sanitized. Exact labels remain capture-required.
