Markdown exportWhen account, login, or rate-limit services are unavailable
Account and rate-limit errors usually protect paid actions and shared request budgets while backend services are unavailable.
What you may see
- Sign in required
- Authentication unavailable
- Rate limit unavailable
- Too many requests
- Invalid or expired API key
- Account or credits could not be loaded
What this means
Invoice Converter uses account and database services to identify users, protect paid actions, store task state, and enforce shared rate limits. If those services are unavailable, some actions are blocked instead of continuing with incomplete account checks.
What to do
- Refresh the page.
- Sign out and sign in again.
- Wait until a rate-limit retry window passes before trying again.
- For API use, respect Retry-After and quota headers if provided.
