How to Promote Admins on a Crossplay Space Engineers Server

Published 9 June 2026 · By Host Havoc Technical Support Team

When your Space Engineers server uses crossplay (EOS networking), the standard Steam64 ID method cannot be used to promote admins. Instead, use the VRage Remote Client included with the Space Engineers Dedicated Server tool.

Before you start

  • Download the Space Engineers Dedicated Server tool from Steam (App ID 298740).
  • The player to be promoted must be connected to the server in-game when you click Promote.

Steps

Get your Remote API credentials

  1. In the Game Control Panel, navigate to Configuration Files and open SpaceEngineers-Dedicated.cfg using Text Editor.
  2. Scroll to the bottom and note the values for <RemoteSecurityKey> and <RemoteApiPort>.

Open VRage Remote Client

  1. On your local computer, navigate to \SpaceEngineersDedicatedServer\DedicatedServer64\ inside the installed Dedicated Server tool folder.
  2. Open VRageRemoteClient.exe.

Connect to your server

  1. In the Connect section of VRage Remote Client, enter:
    • Remote URL: http://<your-server-IP-address>
    • Port Number: the value from <RemoteApiPort> in your config
    • Security Key: the value from <RemoteSecurityKey> in your config
  2. Click Connect.

Promote the player

  1. Once connected, make sure the player to be promoted is in-game on your server.
  2. Locate the player in the VRage client and click Promote.

Troubleshooting

"Warning: Remote API - Invalid date from IP" error

This error occurs when your local computer's time zone differs from the server's time zone. To resolve it:

  1. Change your local computer's time zone to UTC.
  2. Try connecting again.
  3. If it still fails, keep the time zone at UTC and set your clock back one minute. For example, if the time is 12:00, change it to 11:59.

Once adjusted, the connection should succeed normally.
