## Verbindungsabbrüche und mehrere Clients handhaben { #handling-disconnections-and-multiple-clients }

Wenn eine WebSocket-Verbindung geschlossen wird, löst `await websocket.receive_text()` eine `WebSocketDisconnect`-Exception aus, die Sie dann wie in folgendem Beispiel abfangen und behandeln können.
