In LiveStats V6 there are 2 port numbers that can be used for Webcasting purposes.
Users can check the Port Number settings via Tools > Configuration > General
The default Port Number in LiveStats V6 = 80 which should suffice in most venues however if users are experiencing issues with the Webcast when using this default setting (e.g. unable to connect or maintain Webcast connection), the Port Number can be changed to 5522 instead.
At this point LiveStats should be restarted and the Webcast tested again.
