save, pause and the toggles) show a confirmation after a short wait — that's expected. Your RCON password is relayed over an encrypted HTTPS request and is never stored or logged.
The Isle Evrima RCON Tester FAQ
Evrima does not use the Valve Source RCON protocol that most games and tools (mcrcon, rcon-cli, Rusty) expect. It uses a custom binary protocol: an auth packet of 0x01 + password, then command packets of 0x02 + an opcode byte + comma-separated arguments. This tool speaks that protocol for you.
Stop the server, open the Game.ini config file (Saved\Config\WindowsServer), and under [/script/theisle.tigamesession] set bRconEnabled=true, RconPassword=your_password and RconPort=8888. Restart the server and make sure TCP port 8888 is open in your firewall or panel. The RCON listener only becomes available once the server has fully started.
That's an Evrima-specific quirk: multi-argument commands are sent with commas inside a single argument string, e.g. directmessage 76561198000000000,Hey there or ban PlayerName,76561198106341655,Cheating,0. Getting the order or commas wrong makes the server silently ignore the command.
Commands like save, pause, wipecorpses and all the toggle commands act silently — the server doesn't send any payload back. The tool waits a moment and confirms the command was sent. Commands that do return data (playerlist, serverdetails, getplayerdata, getqueuestatus) show the server's response in the console.
Your password is sent over an encrypted HTTPS POST to relay your RCON session and is never stored, logged, or cached. Only the game server you entered receives it. Keep it private — anyone with the RCON password has full admin control of your server.
Common causes: the server is offline or still starting, you entered the game port instead of the RCON port, bRconEnabled is false, the password is wrong or has stray spaces from Game.ini, or TCP 8888 is closed in the firewall/panel. Also note the tool only accepts public IPs and domains — the server must be reachable from the internet.
