So I have been trying to get my own server setup for Atlas, before I say more this is not my first server. I used to run my own web server, still run my own Ark server, Rust server, 7 Days to Die server. I have gotten the server running on my laptop(which right now is my server machine), I can log into the game via Laptop(same machine as server), Can see the server on a different machine on the same LAN via Steam Servers but cannot connect to the server. game server is setup using external IP for the Server Address, all ports have been opened for the game using the port forwarding in my dumb isp/router. I even disabled my Windows Defender fully(even though the server is allowed the passthrough). What are some of the steps you guys have taken to get the server to work on SAME LAN but different machines for server and clients
