Map common error classes to a safe recovery action while preserving the original response and request context.

Best for: Administrators, operators, integrators, and support.

Before you start

Viewing or changing billing, provider credentials, roles, and device licenses requires appropriate access.

  • Use the current production release and approved organizational policy.
  • Record resource IDs, exact time zone, and accountable owner.
  • Validate in a non-production environment when possible.
  • Record exact status, endpoint/action, correlation/request ID if shown, time, user role, and app/browser version.
  • Redact authorization headers and secrets.
  • Check status.4all.live before repeated retries.

Step by step

  1. 400/validation: correct missing/invalid fields, language, state, or incompatible option; do not retry unchanged.
  2. 401/unauthorized: session/token is absent, expired, or invalid; sign in/authorize again and verify system time.
  3. 403/forbidden: identity is known but role, team, entitlement, plan, policy, or active organization blocks the action.
  4. 404/not found: verify organization/team/event/resource ID and whether it was archived/removed.
  5. 408/425/timeouts/too early: retry only when the operation is idempotent and network is stable.
  6. 429/rate or quota: stop rapid retries, respect backoff, inspect provider quota/usage/wallet, and use an approved fallback.
  7. 500/502/503/504: capture the first response, check platform/provider status, retry with backoff, and escalate if persistent.
  8. Wallet/usage exhausted: an authorized billing owner must fund/upgrade or switch to approved BYOK/provider behavior.
  9. Device-license limit: known active devices may reactivate, but a new device requires freeing a slot or purchasing capacity.

What success looks like: The error is classified and resolved without unsafe retries, privilege bypass, duplicate creation, or secret exposure.

Check your setup

  • Original code/message is preserved.
  • Recovery matches the class.
  • Repeated attempts use backoff/idempotency.
  • Billing/license changes are performed by authorized owner.

Troubleshooting

  • 403 treated as bad password: verify role/team/entitlement instead.
  • 429 storm: stop automation and wait the advised interval.
  • 5xx on one provider only: isolate provider and use approved fallback.
  • License blocked: revoke only a confirmed inactive device.

Security and operational notes

Important: Never bypass authorization, plan, quota, or licensing enforcement by altering client data or sharing another user's credentials.
