Can't join LAN Server in Server Administration Posted June 16, 2020 · Edited June 16, 2020 by Snekondplace Can't join LAN Server Hello, so i am trying to create a LAN Server for roughly 3 Days now. I have 2 PC's in my room. One with Windows 10 (My Gaming PC) and the other one with Debian 10 (Hosting Machine). On the hosting machine i installed an ARK Server and it's running how it supposed to run. But when i try to connect with my Win10 Machine, i get this error: "Unable to query server info for invite". Things i have done so far: 1. Reinstalling ARK 2. Adding rules to the Win10 Firewall 3. Adding rules to the iptables in Debian 10 4. Reinstalled the Server several times 5. I even tried to create a LAN Server on my Win10 Machine but i got the same error. Can someone help me? Or do i have to rent a server in order to play with my brother? //EDIT #1 I can't really open ports in my router. In germany we have this thing called DSLite and it basically won't let you forward ports. And due to DSLite i only have an IPv6. I also tried to run the LAN Server with an Software like ZeroTier wich is like Hamachi. But still no success.
