Description

When the UI attempts to connect to the backend service and the connection fails (e.g., backend is down, incorrect API end point, or network issues), the UI currently displays a blank white screen without any informative error message.

Expected Behavior

Upon a backend connection failure, the frontend should:

• Display a clear, user-friendly error message indicating that the application cannot connect to the server.
• It should not render a blank screen. If the initial data fetch fails, a dedicated error component or a fallback 404-like page should be rendered instead.
