Codex or Claude Stopped Working? Diagnose the Error First

A failed request is not necessarily a ban. Check the exact error, active account and billing state before changing anything.

Kelvin Wong·Updated 2 October 2026·3 min read

A usage-limit message, an expired login and a suspended account need different fixes. Advice about keeping the same IP address cannot tell you which problem you have. Save the exact wording and the time it happened before signing out, replacing keys or paying for another plan.

Match the symptom to the next step

SymptomFirst check
OpenAI API 401The selected key, organization and project permissions.
OpenAI API 403 unsupported regionThe published location policy; adding credit does not change it.
OpenAI API 429Read the error code: rate, credit and spending limits require different actions.
OpenAI API 500/503A server problem or capacity issue; check status and retry according to the response.
Explicit account suspension noticeThe stated reason and official appeal route, not a new paid account.

The API rows above follow OpenAI’s error reference; browser messages may use different wording. For Claude, Anthropic’s appeal page lists policy violations and unsupported-location account creation among suspension reasons. It provides an appeal form after signing in to the affected account.

Send one useful support report

  • Include the account email, product, exact error, time and timezone, and whether the problem affects all tasks or one request.
  • For API problems, include the request ID and model when available. Remove API keys, passwords and private customer data from logs.
  • For billing problems, include the receipt reference and last four card digits only if requested through official support.
  • If the account may be compromised, secure the email and revoke exposed credentials. Keep a record of unexpected activity for the provider.

Keep access recoverable

Use an account you control, retain receipts and recovery methods, and check the policy for the place where you use the service. No article can promise a ban-proof combination of SIM, card and network. If a restriction is a mistake, evidence about the affected account is more useful than a new identity.
