Hello, I'm a new sys admin that is starting out with self-hosting a Minecraft server. I've noticed that randomly my server will drop its IP address. I am still able to login if I slap a monitor and keyboard to it, but the router just refuses to see it. I have posted the logs right before the server looses its assignment. the way i have been able to fix this is by turning it off and back on, but is there a more permanent solution to this problem that I'm missing? Any help would be appreciated.
