Claude Not Working? Status Checks and Fixes

If Claude isn’t working, the cause is usually one of a handful of common issues — an outage, a login problem, a usage limit, a browser issue, or a network problem. This guide walks through the most common reasons Claude may not be responding and how to fix each one.

ClaudeAIHub. For official Claude status, check status.claude.ai.

Step 1: Check Claude’s Status Page

Before troubleshooting your device or account, check whether Claude is experiencing a known outage or service disruption:

Official status page: status.claude.ai

This page shows real-time status for claude.ai, the Anthropic API, and Claude’s mobile apps. If there’s an active incident or maintenance, you’ll see it here. In that case, the fix is simply to wait — there’s nothing you can do on your end until the service is restored.

See our Claude service status guide for more on reading the status page and what different incident types mean.

Common Problems and Fixes

Claude Won’t Load

If claude.ai loads as a blank page or never finishes loading:

• Hard refresh the page: Ctrl + Shift + R (Windows/Linux) or Cmd + Shift + R (Mac)
• Clear your browser cache and cookies for claude.ai, then reload
• Try a different browser (Chrome, Firefox, Safari, Edge)
• Disable browser extensions temporarily — ad blockers and privacy extensions can interfere with Claude
• Try opening Claude in a private/incognito window
• Check if Claude is loading on a different device (phone, tablet) — if it works there, the issue is likely browser-specific

Claude Login Not Working

If you can’t sign in to Claude:

• Make sure you’re using the correct email address — check if you signed up with Google, Apple, or a different email
• Use “Forgot Password” to reset your password if you’re unsure of it
• Check your spam folder for the login or verification email
• If using SSO (Google or Apple), make sure you’re signing in with the same method you used when you created your account
• Clear cookies for claude.ai and try again
• Check status.claude.ai for auth-related incidents

See our Claude login guide for step-by-step sign-in instructions for web, mobile, and desktop.

Messages Not Sending or Failing

If your messages time out, return errors, or Claude stops mid-response:

• Check your internet connection — Claude requires a stable connection
• Try refreshing and sending the message again
• If a very long message is failing, try sending it in shorter segments
• Check status.claude.ai for API or service disruptions
• If responses cut off mid-sentence, Claude may have hit its output limit — ask it to continue (“Please continue”)

Usage Limits Reached

Claude has usage limits that vary by plan. If you see a message saying you’ve reached your limit:

• Free plan: Usage limits apply and reset periodically. You may need to wait before continuing.
• Claude Pro: Has significantly more usage than the free plan. Upgrade to Pro if you regularly hit free plan limits.
• Claude Max: Offers 5x or 20x more usage than Pro — designed for heavy daily use.

See our Claude plans guide for a full comparison of what each tier includes.

Claude App Not Working (iOS or Android)

If the Claude mobile app is crashing, not loading, or behaving unexpectedly:

• Force close the app and reopen it
• Update the app from the App Store (iOS) or Google Play (Android) — an outdated app version can cause issues
• Check your phone’s internet connection — switch between Wi-Fi and mobile data to test
• Sign out and sign back in
• If problems persist, uninstall and reinstall the app
• Check status.claude.ai for mobile app incidents

Claude Desktop App Not Working

If the Claude desktop app (Mac or Windows) isn’t working:

• Quit the app completely and relaunch it
• Check for app updates — the desktop app is updated regularly
• Check your firewall or security software — it may be blocking the app’s connection to Claude
• Try using claude.ai in a browser as a temporary workaround
• If the app won’t open at all, try uninstalling and reinstalling

Browser or Cache Issues

Browser cache and cookies can cause unexpected behavior on web apps:

• Clear cache and cookies specifically for claude.ai (not your entire browser)
• Try a different browser to confirm if the issue is browser-specific
• Disable browser extensions (especially VPNs, ad blockers, and privacy extensions) and test again
• Try private/incognito mode

Network or Regional Problems

In some cases, network conditions can affect Claude’s performance:

• Check if your network connection is stable
• If using a VPN, try disabling it temporarily
• Claude is available in most countries, but check Claude’s supported countries if you’re unsure about your region
• Corporate firewalls sometimes block AI tools — contact your IT team if you’re on a work network

Account or Session Issues

If Claude is behaving unexpectedly within your account:

• Sign out and sign back in to refresh your session
• Check if you’re logged in to the correct account (if you have multiple emails)
• If a Project or conversation is not loading, try creating a new chat to test

When to Contact Anthropic Support

• Use the Help or Support option within the Claude app
• Visit support.claude.com for help articles and contact options
