Send messages from Android to Windows TCP CLient

Send messages from Android to Windows TCP CLient

How can I send messages from an android test application to a Windows  version of the "TMSLogging TCP Client" application? They both are connected to the same network.

It works from Windows to Windows(same machine), but not from Android to Windows.
I'm using the code

TMSLogger.RegisterOutputHandlerClass(TTMSLoggerTCPOutputHandler, [Self, '192.168.29.30', 8887]);

 and

TMSLogger.Debug('This is a test');
