either JTAlert is not listening for connections on your local subnet (192.168.0/8) or your firewall is blocking it. Since JTAlert requires that WSJT-X be run on the same host as itself you should use either 127.0.0.1 or better still a suitable multicast group IP address like 239.255.0.0. Set that in WSJT-X "Settings->Reporting->UDP Server".

Bill,

My guess it is a firewall/pc protection issue.

JTAlert doesn't listen to any explicit IP, or subnet. The socket binds to a local endpoint using IPAddress.Any
The relevant code...
var localEp = new IPEndPoint(IPAddress.Any, port);
serverSocket.Bind(localEp);
