How to Fix ChatGPT Not Responding

Fix ChatGPT when it stops responding with these proven troubleshooting steps. Check server status, clear cache, and resolve connection issues quickly.

1. Check OpenAI server status. Navigate to status.openai.com in your browser. Look for any red indicators showing service disruptions or degraded performance. If servers are down, wait for resolution as no user actions will restore service during outages.
2. Refresh the ChatGPT page. Press Ctrl+F5 (Windows) or Cmd+Shift+R (Mac) to perform a hard refresh. This clears cached elements and reloads all page resources. Wait 10 seconds for the page to fully load before attempting to send messages.
3. Clear browser cache and cookies. Open your browser settings and navigate to Privacy or Clear browsing data. Select cookies and cached files for chat.openai.com specifically, or clear all data from the past 24 hours. Restart your browser after clearing.
4. Disable browser extensions. Open an incognito or private browsing window and test ChatGPT. If it works, return to normal browsing and disable extensions one by one, testing ChatGPT after each. Ad blockers and privacy extensions commonly interfere with ChatGPT's functionality.
5. Switch networks or restart your router. Test ChatGPT using mobile data if you were on Wi-Fi, or vice versa. If switching networks resolves the issue, unplug your router for 30 seconds, then plug it back in. Wait 2-3 minutes for full network restoration.
6. Try a different browser. Open ChatGPT in Chrome, Firefox, Safari, or Edge if your current browser isn't working. This isolates whether the issue is browser-specific or system-wide. Ensure the alternative browser is updated to the latest version.
7. Log out and back into ChatGPT. Click your profile icon in the bottom-left corner and select Log out. Wait 30 seconds, then sign back in with your credentials. This refreshes your session tokens and clears any authentication conflicts.
