When ChatGPT is not working, start with the safest checks before changing passwords, deleting data, or assuming the account is broken.
Use this guide as a practical starting point, then verify pricing, product limits, and current features before making a final decision.
Start with the real job
Identify the symptom first: login loop, blank screen, slow response, network message, model unavailable, billing issue, or browser-specific failure.
What to compare
Compare likely causes by checking the status page, another browser, a private window, extensions, VPN, network restrictions, account plan, and recent product changes.
Risks and limits
Avoid entering credentials into unfamiliar pages, installing random fix tools, or disabling security settings just because a troubleshooting article suggests it.
Next step
Use the ChatGPT Error Checker to choose the safest first step for the symptom you are seeing.
