I and my friend can create a new server to play multiplayer, but it's invisible to each other. When we try to create a new one and we switch from lan to internet we see the following error: "please ensure your computer has internet accessibility via the following network ports: 2302, 2303". If we change the port from 2302 to 2303, also the message changes augmenting by one the number of the ports and becoming as the following text: "please ensure your computer has internet accessibility via the following network ports: 2303, 2304". We can create the server but it will become invisible. If we switch from internet to lan the error disappears, but if we switch another time from lan to internet it will appear again.
