First time trying to setup.
I have the panel running on one server.
Then I have another oracle ARM server running wings / game servers.
Both servers connect fine.
When I try to create a Minecraft server for quick testing, I get the above error.
On my Oracle VM, I have set Ingress to allow all ports.
I have set allocations of ports Default Allocation: 2001, Additional Allocation(s): 2002, 2003
Then for example on Rust settings, I set Query Port: 2001, RCON Port: 2002, App Port: 2003
