Client Side can't disconnect or dispose

[boxu2018]

once client has been connected with server, i'd like to disconnect the client,
so use method :client.disconnect() or client.dispose();
there will throw exception, like this: System.OperationCanceledException:“The operation was canceled.”

Can you supply a stack trace? I've added some catches for both OperationCanceledException and TaskCanceledException going into 3.0.17.
