Fix ConnectionRefusedError

✅ Solution

ConnectionRefusedError in Chainlit usually means the frontend can't connect to the backend server, often due to the server not running or being blocked by a firewall. Ensure your Chainlit server is started correctly (e.g., using `chainlit run your_app.py`) and that no firewall rules are preventing connections to the server's port (typically 8000). Check the console output for any errors during server startup to diagnose further issues.
