The “Claude Not Responding” message is one of the most common issues users face when using Claude 3.5 and newer models. It usually happens because of browser problems, server overload, or temporary model resets. This guide shows simple, fast fixes that work even for complete beginners.
Who Is This For?
This guide is designed for creators, students, writers, and anyone who relies on Claude for daily tasks and needs quick solutions without technical complexity.
1. Check If Claude Servers Are Down
Before trying anything else, check whether Claude is having a global outage. Sometimes the model pauses due to extreme traffic or maintenance.
2. Refresh the Chat or Open a New Thread
“Not Responding” often means the current conversation is stuck. Opening a new chat forces the model to restart its context and fixes the issue instantly.
3. Clear Your Browser Cache
Old cookies and cached scripts can break Claude’s UI. Clearing them almost always solves sudden freezing or infinite loading.
- Go to browser settings
- Clear “Cookies & Cached Files”
- Restart your browser
4. Turn Off Browser Extensions
Extensions like ad blockers, script injectors, and VPN plugins can interfere with Claude. Try disabling them temporarily.
5. Try a Different Browser
Claude works best on Chrome, Edge, and Arc. If you’re using Safari or Firefox, the UI may freeze or delay responses.
6. Reduce Message Length or Split Tasks
Claude may stop responding if a message is too long or requires heavy reasoning. Splitting the task into smaller steps helps keep the model stable.
7. Check for Network Issues
A slow or unstable internet connection is one of the main causes of freezing. Restarting your router often fixes this instantly.
8. Use Claude Desktop or Mobile App
If the browser version keeps freezing, try using Claude’s standalone app for smoother performance.
