What drives people crazy most when using ChatGPT usually isn’t not knowing how to use it, but suddenly being unable to log in, messages failing to send, or the page seeming “broken.” Below, I break down the most common issues by scenario and provide ways you can immediately self-check, with as little detouring as possible. When you run into a similar situation, troubleshoot in order first—often you can restore normal ChatGPT use within a few minutes.
Login restrictions and frequent CAPTCHAs: Start with the browser and network
If ChatGPT keeps prompting CAPTCHAs during login, common causes include browser cache, extension injection, or abnormal network egress. First, open ChatGPT in an incognito/private window, disable ad-blocking/script-related extensions, then clear the site’s cookies and log in again.
If you keep seeing “Access restricted,” switch to a more stable network route and make sure your system time is set to sync automatically; a time mismatch can cause session verification to fail. If it still doesn’t work, try switching browser engines (e.g., Chrome ↔ Edge) and then access ChatGPT again.
Unable to send messages or request errors: Start with content and rate
If ChatGPT fails to send messages, first shorten what you’re entering—remove extra-long links, large blocks of code, or lots of tables—and send it in multiple parts. Submitting repeatedly in quick succession can also trigger rate limits; waiting a few minutes and trying again usually restores normal operation.
If you encounter “Request error / Network error,” refresh the page and reselect the conversation; also check whether you’ve enabled proxy rules or security software that rewrites web requests. If necessary, log out and log back in so ChatGPT can re-establish the session token.
