# When validation is unavailable

- 2026-08-29

A temporary validator outage blocks the selected profile check; it does not show whether the invoice facts are correct.

## What you may see

- Profile validation is temporarily unavailable
- KoSIT validation unavailable
- Validation service unavailable
- Validation proof unavailable

## What this means

Invoice Converter can run review checks, but final export also validates the generated file against the selected profile and ruleset version. If that validator service is starting, unhealthy, or unreachable, the page pauses export.

## What to do

- Fix any visible invoice data errors first.
- Wait a short time and run validation again.
- For production e-invoices, wait for validation to pass before sending the file to a buyer or portal.
