User story

As a user who is willing to setup Unreal Tournament server for multiple people I would like to have it working.

Game

Unreal Tournament

Linux distro

Ubuntu 24.04

Command

command: start

Further information

Apparently, the current (2025-08-30) default setup of Unreal Tournament game server (utserver), does not have the proper list of master servers. So the game server can not initialize.

As far as I understand, this file (or its parts, "ServerActors"): https://github.com/GameServerManagers/Game-Server-Configs/blob/main/ut99/Default.ini should be used. However, I was not able to find how to properly adjust the existing configs. Could you please help with finding out what I am missing?
