Can't join LAN Server
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".

1. Reinstalling ARK
2. Adding rules to the Win10 Firewall
3. Adding rules to the iptables in Debian 10
4. Reinstalled the Server several ti
