I just wanna play a game with one other person, but I have to create a whole internet server and every single tutorial I've found doesn't work. The batch files thing doesn't work anymore and the newer way of doing it won't let others be able to see the server due to me not hating the correct login or something. I've never seen a game that's this multiplayer focused not just have a way to play a private game with friends
External link →My assumption is that the error message regarding "not having the correct login or something" is probably the one telling you that you haven't added a Game Server Login Token (GSLT) from Steam to your server yet, whoch is why it isn't appearing in the Steam server list.
Refer to official documentation for server hosting: https://github.com/SmartlyDressedGames/U3-Docs/blob/master/ServerHosting.md
For generating a GSLT specifically, see: https://github.com/SmartlyDressedGames/U3-Docs/blob/master/GameServerLoginTokens.md
