How to Fix Claude Not Working

Claude AI can stop working due to browser issues, server problems, or account limitations. These troubleshooting steps resolve the most common problems that prevent Claude from responding or loading properly.

1. Check Claude's server status. Visit status.anthropic.com to verify Claude's services are operational. If there's a reported outage, wait for Anthropic to resolve the issue. Server problems appear as widespread connection failures across all users.
2. Clear your browser cache and cookies. Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac) to open browser settings. Select 'All time' as the time range and check 'Cookies and other site data' and 'Cached images and files'. Click 'Clear data' and restart your browser.
3. Disable browser extensions. Open an incognito or private browsing window and navigate to claude.ai. If Claude works in incognito mode, your extensions are interfering. Disable ad blockers, privacy extensions, and script blockers one by one to identify the problematic extension.
4. Update your browser. Click the three-dot menu in Chrome, select 'Help' then 'About Google Chrome'. For Firefox, click the hamburger menu, select 'Help' then 'About Firefox'. Allow the browser to download and install updates, then restart.
5. Check your internet connection. Test other websites to confirm your connection is stable. If using WiFi, move closer to your router or switch to cellular data. Run a speed test to ensure you have at least 1 Mbps for basic Claude functionality.
6. Verify your account status. Log out of Claude completely and log back in. Check if you've exceeded usage limits, which appear as messages about reaching your conversation limit. Free accounts have daily message caps that reset every 24 hours.
7. Try a different browser or device. Open Claude in Firefox, Safari, or Edge if you normally use Chrome. Alternatively, try accessing Claude from your phone or tablet. This isolates whether the problem is device-specific or account-related.
