Server notes

The dedicated server is app id 1690800, pulled anonymously, but **its port scheme changed and a huge amount of online guidance is now stale** — that is the single biggest trap here. Before 1.0/1.1 the model was three UDP ports: 7777 for the game, 15000 for the beacon and 15777 for the query. The live build needs only two: 7777 (TCP for server traffic and the HTTPS API, UDP for game traffic and the lightweight query API) and 8888/TCP for reliable messaging. If a guide tells you to open 15000 or 15777, ignore it. Neither 7777 nor 8888 supports port redirection, so the external and internal numbers must match on your router — you cannot map external 27015 to internal 7777. Satisfactory ships no admin password in a config file; administration works by claiming the server from the in-game Server Manager, where you add it by IP and set an admin password, which binds it to you. The two INI files you tune are Engine.ini (networking and tick rate — NetServerMaxTickRate defaults to 30, an upper bound the server only reaches if the CPU has headroom) and Game.ini. **Just like Project Zomboid, Satisfactory rewrites its INI files on a graceful shutdown**, so every edit must be made while the server is stopped. Hardware demands are an order of magnitude above Valheim (a 3D UE5 factory): plan on 12 GB of RAM to start and 16–24 GB to be comfortable, and reassess for more than a few players.
