How can I debug a 'Network request failed' error?

1) Check your network connection. 2) Verify the API endpoint URL is correct. 3) Use your browser's developer tools (Network tab) to inspect the request and response headers. Look for CORS errors or HTTP status codes other than 200. 4) Try making the request from a different tool (like Postman) to rule out client-side issues. 5) Examine the server logs for any errors.
