Manual Installation of Modpacks

In this guide, we will show you how to manually install modpacks, rather than using the modpack installer on our panel.

Modded servers usually require more resources than a vanilla Minecraft server. We therefore recommend our Advanced plan tier if your intention is to run modpacks on your server.

Download the Modpack

Visit a trusted modpack site (e.g., CurseForge, Modrinth).
Search for the desired modpack.
Download the modpack's server files, which usually come in .zip format.
Save the file to a convenient location on your computer.

Prepare the Modpack for Upload

Ensure the folder contains the necessary files (like mods, config, libraries, and server .jar files).
Make sure all essential files are present.
Make sure the file is in the .zip format.

Access Your UltraServers Panel

Login to the Panel, see for instructions.
Navigate to the server on which you want to install the modpack.
Stop the server to prevent any issues during the upload process.

Upload the Modpack to the Server

Use the built-in Upload button within the Files tab on the UltraServers panel.

Alternatively, connect to the server via SFTP Transfer using a client like FileZilla if the modpack zip is too large.

Delete all existing files in the server's root directory.

Upload the zipped modpack files to the server's root directory.

Now click the ... three dots and click the Unarchive button, and wait.

Files will be extracted in a directory named according to the zip file.

Open this directory and select all the files, and click the Move button.

Enter ../ in the field and click the Move button to move files to the root directory.

Start Server and Play

Once the file is done extracting, click the start server button.
First-time startup on modpacks can take a while, so please wait patiently.
Once the startup is done, you can join your server and enjoy playing!

If you require further assistance, you can open a support ticket here.

Feedback and suggestions can be submitted here, or further discussed on our Discord server.
