Empyrion Server Not Starting: Troubleshooting Guide

Published 9 June 2026 · By Host Havoc Technical Support Team

When your Empyrion server refuses to start, the cause is almost always logged to the console. Open Web Console from your game control panel and read the output before working through the steps below.

Validate the server files

  1. Log in to the game control panel and stop your server.
  2. Open File Manager and delete the steamapps folder.
  3. Click Steam Updater and wait for it to finish downloading before starting the server again.

Re-save the dedicated_config.yaml file

  1. Open Configuration Files in the control panel.
  2. Click Configuration Editor next to dedicated_config.yaml.
  3. Save the file without making any changes. This forces the panel to write a correctly formatted copy.

Remove non-alphanumeric characters from dedicated.yaml

  1. Open Configuration Files in the control panel.
  2. Click Configuration Editor next to dedicated.yaml.
  3. Scan each parameter value for special characters (quotes, dashes, brackets) that do not belong and remove them.
  4. Save the file.

Check the adminconfig.yaml format

A malformed adminconfig.yaml is a common cause of startup failures. Errors in this file are often reported as a dedicated.yaml problem, even though that file is not at fault.

  • Follow the example format in the file exactly.
  • There must be no duplicate entries.
  • Each Steam64 ID must appear only once.

See add admins for the correct format.
