ARK: Survival Ascended RCON Commands: Server Admin Reference
ASA server admin over RCON: enable it with RCONEnabled and ServerAdminPassword in GameUserSettings.ini, why you drop the admincheat prefix over RCON, the EOS ID trap (kick/ban/chat commands take the 32-character Account ID, not a Steam64 ID), permanent-only native bans, the AllowedCheaterAccountIDs.txt admin whitelist, and the commands that actually work - ListPlayers, Broadcast, ServerChat, SaveWorld, DoExit, DestroyWildDinos.
ARK: Survival Ascended kept the genuine Valve Source RCON protocol from ARK: Survival Evolved - any standard Source RCON client connects unchanged. What it did NOT keep is the ID system: ASA moderation commands address players by their EOS ID, not a Steam64 ID, and getting that wrong is the single most common reason a kick or ban silently does nothing. This reference covers what actually works over RCON on ASA.
This guide is for ARK: Survival Ascended. Running legacy ARK: Survival Evolved? Its commands differ (Steam64 IDs, Workshop mods) - see the ARK: Survival Evolved RCON reference.
Enabling RCON
RCON is configured in GameUserSettings.ini under [ServerSettings] - the file lives in ShooterGame/Saved/Config/WindowsServer/ (the path says WindowsServer even when you run the server under Wine or Proton on Linux, because ASA ships Windows server binaries only):
