Exception	Exception.Message	Scenarios
ESocketError	Network socket error: <error message> (<error code>), on API 'closesocket'	The operating system reported an error while closing the socket. For more information, see the following documentation for the operating system where your application was running: Windows: closesocket function (MSDN) OS X: close (OS X Man Pages) iOS: close (iOS Manual Pages) Android: close (Linux Programmer's Manual)
	Network socket error: <error message> (<error code>), on API 'shutdown'	The operating system reported an error while gracefully shutting down the current connection of the socket. This may happen if you do not force closing the socket (ForceClosed is False) and the type of your socket is not UDP. For more information, see the following documentation for the operating system where your application was running: Windows: shutdown function (MSDN) OS X: shutdown (OS X Man Pages) iOS: shutdown (iOS Manual Pages) Android: shutdown (Linux Programmer's Manual)
