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