TcpSocketListener stops receive after first time

[Tical-]

Hi, TcpSocketListener stops receive after first time.

public TcpSocketListener listener;
var listenPort = 8912;
listener = new TcpSocketListener();
listener.ConnectionReceived += DO;
AsyncHelpers.RunSync(async () => await listener.StartListeningAsync(listenPort));

I try to reinit this. Do not working:
listener.StopListeningAsync();
listener.Dispose();
listener = new TcpSocketListener();
listener.ConnectionReceived += DO;
AsyncHelpers.RunSync(async () => await listener.StartListeningAsync(8912));
listener.ConnectionReceived += DO;
I dont know, why
