Before you start

Separate web chat, file uploads, voice and API access; a web subscription does not provide API credits.

Step by step

  1. Confirm the official entry point through https://help.openai.com/. Avoid unfamiliar sign-in pages.
  2. Use one device and one network exit to open ChatGPT; identify whether the home page, sign-in redirect or actual feature fails.
  3. Separate web chat, file uploads, voice and API access; a web subscription does not provide API credits.
  4. Compare a short message in a new chat with an upload of one small file; record which stage fails.
  5. For 401 or 403, check account status and the displayed message before changing network settings.
  6. Change one condition at a time; if an official incident is active, follow the provider’s updates.

Common questions

Can switching networks fix every ChatGPT error?

No. Account privileges, subscriptions, file permissions and service outages require separate checks.

What should I send to support?

Share the time, client version, redacted error code and minimal reproduction. Never share a password, token, cookie or one-time code.
