Connection Handling

The TUI tracks connection state to the Hop3 server:

• Connected (green indicator): Server is reachable
• Disconnected (red indicator): Connection lost, will retry
• Connecting (yellow indicator): Attempting to connect

Connection failures are tracked and the state updates automatically. The UI continues to show cached data while disconnected.

Development
