How to Setup a Hytale Server

Follow this step-by-step guide to host your own Hytale server for you and your friends.

Prerequisites: Make sure you have HyLauncher installed and have run the game at least once to generate the necessary files.

1 Install Java JDK 25

Hytale servers require Java Development Kit (JDK) 25 to run properly. If you don't have it installed:

Download JDK 25 from Adoptium

Follow the installation wizard and make sure to add Java to your system PATH when prompted.

2 Download HyOffline.jar

You need to download the HyOffline plugin that enables offline server functionality.

Download HyOffline.jar

Note: Yes, you need this file to be able to join the server using HyLauncher. Your friends must be using HyLauncher or the official launcher.

3 Navigate to Your Game Files

Open your Hytale installation folder. You should see a structure similar to this:

Locate the Server folder inside your game directory.

4 Place HyOffline.jar in Server Folder

Move or copy the downloaded HyOffline.jar file into the Server folder.

5 Create Start Server Script

Inside the Server folder, create a new file called start-server.bat and add the following content:

start-server.bat

@echo off
java -javaagent:HyOffline.jar -jar HytaleServer.jar --assets ..\Assets.zip --auth-mode offline
pause

6 Start Your Server

Simply double-click the start-server.bat file you created. A console window will open and your server will start.

Note: The first startup may take a few moments as the server generates necessary files and loads assets.

7 Allow Friends to Connect (Port Forwarding)

By default, your server only runs locally. For friends to join, you need to set up port forwarding using a service like PLAYIT.gg:

Visit PLAYIT.gg

PLAYIT.gg provides free tunneling so your friends can connect without complex router configuration.

Tutorial: Search YouTube for "how to setup playit.gg" for detailed video guides on configuring the tunnel for your server.

8 Share Server Address

Once PLAYIT.gg is configured, you'll receive a server address (e.g., example.gl.at.ply.gg:67420).
Share this with your friends so they can connect to your server!

Troubleshooting: If your server won't start, make sure you have JDK 25 installed, HyOffline.jar is in the correct folder, and the Assets.zip path in the bat file is correct.
