Server not giving display output nor can I connect to the GUI after 10 minutes

[CaptainTim]

Hi, so ofc I am kind of a newbie on all of this server stuff but I do have a good general knowledge of tech. But I have recently installed truenas scale on my server and after around 10 minutes of having the server on it stopes giving a display output and I lose connection through the web GUI. The server is still on and is running and it was working before as a windows system.
