to verify that the port is actually open and visible run cmd.exe as admin and type:
netstat -abn
you will see a list of image names look for Cube.exe or whatever the image name is and see what port is open ( if any ).
here is an example on my system with an image called test_framework.exe which has initialized wwise and opened communication on port 63171/63983
[test_framework_default.exe]
TCP 0.0.0.0:63171 0.0.0.0:0 LISTENING
[test_framework_default.exe]
UDP 0.0.0.0:63983 *:*
hope that helps
