Steam requires a Game Server Login Token (GSLT) for many dedicated sessions.
Create
- Open Steam’s Game Server Login Token page while logged into Steam.
- Create a token for the correct app ID (ATS 270880 / ETS2 227300 — verify current Steam UI).
- Copy the token once.
Install
- Stop the server in Pterodactyl.
- Paste the token into the appropriate field in
server_config.sii. - Start and confirm the console does not report token errors.
Never commit tokens to public repos or leave them in KB screenshots.
