networkTcpClientExample Error


I’m building and running oF 007 addon examples, networkTcpClinetExample and networkTcpServerExample.
After I run the server and the client, I got the following error message.

OF: OF_LOG_ERROR: ofxNetwork:…\addons\ofxNetwork\src\ofxTCPManager.cpp:157 ECONNREFUSED: the server has actively refused to establish the connection
ofxTCPClient: Connect(, 11999) failed

What’s wrong with this example?

Any help?
