💡 Frequently Asked Questions (FAQ)
- Q: Why am I getting Unexpected status 401 on ChatGPT?
- A: A 401 error means unauthorized access. It often occurs due to expired sessions, account restrictions, API key issues, or temporary server-side outages. Try logging out and back in, clear cache, and check OpenAI service status.
- Q: Why is Codex suddenly inaccessible?
- A: Codex access can be limited by plan restrictions, regional availability, or deprecation of features. Check your subscription tier, ensure you’re on a supported device, and verify if OpenAI has moved or renamed the Codex tool.
- Q: Why did Work Mode and Model Picker disappear on mobile?
- A: Mobile UI changes, A/B testing, app updates, or account type limitations can hide Work Mode and Model Picker. Update the app, switch to desktop view, or reinstall the app to restore the features.
- Q: How can I quickly fix ChatGPT down issues?
- A: Refresh the page, clear browser cache, try incognito mode, switch networks, check Downdetector and OpenAI status page, and log out/in. If persistent, wait for server recovery or use the official app.
