Learn how to use the Installer and Modpack section of the control panel to install modpacks
Step 1) Stop your server
Step 2) Go to Settings --> Installer and Modpack section
Step 3) Search for the modpack you would like to install. Note: If the modpack is not there, or it is outdated, contact our support team to install and update for you
Step 4) Click Install and then click Fresh Install
Step 5) Start Server!
Don't forget, all clients who want to join the server must also install the same modpack with the same version on their device or they will not be able to join.
Use the modpack's recommended laucher (eg AtLancher, CurseForge, FTBLauncher) for easy installation of the modpack on the client.
Contact our support team if the modpack version is outdated
