ChatGPT Troubleshooting Guide: Fixing Network Errors, 429 Rate Limits, and Unavailable Conversations

If ChatGPT won’t open, keeps spinning, or says the request failed, it’s usually not that “the model is broken,” but rather an issue with your network, browser cache, rate limiting, or session state. Below, we break down ChatGPT troubleshooting by symptoms and provide step-by-step fixes you can follow directly.

Start with three quick checks to pinpoint the cause and avoid detours

Step 1: Check service status: open status.openai.com. If core components are down, wait for recovery before tinkering locally. Step 2: Verify by switching environments: log in once with the same account on mobile data / another device to determine whether it’s a network issue or a browser issue.

Step 3: Minimize interference: turn off proxies/VPNs/accelerators, ad blockers, and script extensions, then access ChatGPT in an incognito window; many “failed to load” cases are actually caused by extensions blocking requests.

How to fix “Network Error / Request error / Stuck loading”

For this type of ChatGPT issue, prioritize cache and connection fixes: clear your browser cache and cookies (clearing only chat.openai.com is fine), then hard-refresh the page. If you’re on a corporate or campus network, try switching to a mobile hotspot—some networks restrict WebSocket/HTTP2.

Also check whether your device time is set to sync automatically; a large time drift can cause authentication to fail. For desktop or mobile app users, update to the latest version and then sign in again to avoid incompatibility between older versions and the API.

What to do when you see “Too Many Requests / 429 / High load”

A 429 is essentially rate limiting, not that your account is “broken.” Stop for 1–3 minutes before sending again; avoid repeatedly clicking Send quickly, and don’t keep many ChatGPT tabs open and refresh them over and over.

If you frequently edit and resend in a long conversation, or ask it to process very large blocks of text, you’re also more likely to trigger rate limits. The fix is to start a new chat and split your request into smaller chunks—this trick saves a lot of time in ChatGPT troubleshooting.

How to troubleshoot “Conversation unavailable / Login loop / Unable to load conversation”

Log out and log back in, and in settings restore any “remember me”–related site permissions to default. If the login page keeps redirecting back and forth, it’s usually because cookies are blocked or intercepted by a cleanup tool—make sure third-party cookies are allowed (or at least allow OpenAI-related domains).

If a conversation fails to load, first copy any draft input you can still see, then start a new chat and continue. If only the history list is missing, waiting a few minutes and refreshing usually restores it. If the issue persists, use the results from the status page and your network switching test to decide whether to contact support; providing screenshots and the exact error text helps pinpoint the root cause faster.
