ChatGPT Not Responding? 7 Fixes That Actually Work

Why ChatGPT Stops Responding

ChatGPT hangs due to server overload, corrupt browser session, extension conflicts, or rate limits. Start with the quickest checks first.

Fix 1: Check OpenAI Server Status

Visit status.openai.com. If there is an ongoing incident, wait — no local fix will help.

Fix 2: Hard-Refresh the Page

Press Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac) to bypass the browser cache.

Fix 3: Clear Cookies for chat.openai.com

DevTools → Application → Cookies → Delete all for chat.openai.com. A corrupted session token is a common culprit.

Fix 4: Disable Browser Extensions

Ad blockers and VPN extensions intercept the streaming response. Open Incognito (disables most extensions) and test.

Fix 5: Switch Browsers

ChatGPT uses Server-Sent Events for streaming. Some browsers handle this better. Try Firefox or Edge if Chrome is the problem.

Fix 6: Reduce Conversation Length

Long threads can exceed the context window. Start a New Chat and paste only the essential context.

Fix 7: Check Usage Limits

ChatGPT Free users face hourly caps on GPT-4o. Check Settings → My Plan — if you hit your limit, the response window appears to hang.
