Advanced Sessions Network error: Connection TimeOut - LAN

Hi
I have an error with “Advanced Session” plugin, the problem is when I try to connect with 2 different PC using LAN, the client connect to the server session, but don’t open the server map, and show the network error: connection timeout. The server is a listen server.

(We use a switch without internet, we assign the static IP to each PC, the sub-network mask, etc. The unique options we don’t configure are the DNS, but I don’t believe that’s for that).

The errors are this:
