Step-by-Step Configuration Guide

Select Server Type

Create a server on FreeGameHost. Under the Startup settings, change the server engine type to Forge or Fabric. Check the server console panel logs as the startup sequence runs to verify that no error exceptions or missing dependency logs are thrown.

Generate Server folders

Start the server once to let the system generate files and then click Stop. This creates the 'mods' folder. Check the server console panel logs as the startup sequence runs to verify that no error exceptions or missing dependency logs are thrown.

Upload Mod Jar files

Open the File Manager, enter the 'mods' folder, and upload the mod .jar files downloaded from Modrinth or CurseForge. Make sure to select the build version that matches your game server software exactly to prevent class loading errors during startup.

Client Mod Matching

Install the exact same mods and engine versions on your client PC. Launch Minecraft and join using your server port. Make sure to select the build version that matches your game server software exactly to prevent class loading errors during startup.

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:

# Example of server-side Fabric optimization mods to upload: fabric-api.jar (Required dependency) ferritecore-fabric.jar (Reduces RAM memory footprint by 25%) lithium-fabric.jar (Optimizes physics and entity ticking)

Pro Tip: Client-only mods (like Optifine, inventory HUDs, or minimaps) will crash the server on start. Only upload server-compatible content mods to your server mods folder. Pre-generating world chunks using plugin utilities (like Chunky) is highly recommended for reducing startup lag during exploration.

Frequently Asked Questions

What happens if the server crashes?

Check your console logs or open the 'logs/latest.log' file. Look for 'Missing Dependency' to see if a mod requires a library jar to run.

How much RAM do I need for modpacks?

Basic modpacks run fine on FreeGameHost's free 4GB RAM. Heavy packs (over 150 mods) require 6-8GB.
