Step-by-Step Configuration Guide

Install Server files

Create a game instance and select Sons of the Forest. The server will download the Steam App ID 2465200 files. Make sure to select the build version that matches your game server software exactly to prevent class loading errors during startup.

Configure Server JSON

Open 'SonsOfTheForestServerConfig.json' in the File Manager. Set server name, admin passwords, and player slots. This step is critical for proper server operation. Ensure that you have taken a manual file backup before committing these changes to disk.

Configure server port rules

The game uses query port 8766 UDP and game port 27016 UDP. Configure these in network allocations. Open the file using the built-in Pterodactyl File Manager editor. Ensure you do not use tabs for indentations, as YAML requires spacing rules.

Join and play

Start the server. Open your client, select multiplayer, choose Dedicated Servers, filter by name, and enter your password. Check the server console panel logs as the startup sequence runs to verify that no error exceptions or missing dependency logs are thrown.

Recommended Configurations and Setup Files

To configure your server files correctly, navigate to the File Manager in your control panel and open the corresponding configuration files. Paste or modify the settings as shown in the configuration block below. These lines help prevent database thread blockages, optimize tick timing performance, and reduce entity rendering overhead on the game host:

# SonsOfTheForestServerConfig.json settings: { "ServerName": "My Free SOTF Server", "MaxPlayers": 8, "Password": "forestKey", "AdminPassword": "adminSecret", "SaveInterval": 600 }

Pro Tip: Disable structure damage in the config if you want to protect your elaborate base builds from being destroyed by mutant attacks when offline. Pre-generating world chunks using plugin utilities (like Chunky) is highly recommended for reducing startup lag during exploration.
