Claude Not Working Today? Quick Fixes

If Claude has stopped working, the cause is almost always one of four things: an Anthropic-side incident, a stale browser session, a network or extension conflict, or a plan limit. Work through the checks below in order.

1. Check whether Claude is down for everyone

Open the Claude status page on this site first. If an incident is in progress there is nothing to fix locally — wait it out. Also see Claude not responding for the symptoms of a partial outage.

2. Reload with a clean session

Sign out, close every claude.ai tab, then reopen the site and sign back in. A stale token is the single most common cause of a chat that never replies.

3. Clear cache and site data

In your browser settings, clear cached files and cookies for claude.ai only. On mobile, force-close the app and reopen it. If the screen hangs at the loading spinner, follow Claude app won't load.

4. Disable extensions and VPNs

Ad blockers, privacy extensions and corporate VPNs can block the streaming connection Claude uses to deliver replies. Test in a private window with extensions disabled.

5. Try a second browser or device

If Claude works elsewhere, the fault is local: your profile, network or device. If it fails everywhere on your account, it is account or service side.

6. Check your usage limits

Free and Pro plans both cap messages in a rolling window. Hitting the cap looks like a silent failure rather than a clear error. Wait for the reset window or start a shorter conversation.
