Overview

Having a modded Minecraft server is a great way to customize your gameplay experience. However, playing with mods is not as simple as just uploading them to your server. For every mod that goes into your server, it has to be run client-side. Minecraft by default does not run mods so you need to use a mod loader, Forge. Many times when adding mods, players will use modpack launchers. These are especially useful as they install Forge easily and allow the modpacks to be launched straight from the launchers platform. Some of the most popular modpack launchers include Twitch, Technic, ATLauncher, Voidswrath, and FTB. Adding mods to an existing modpack is quite easy, and we will be walking you through each step on how to.

This tutorial does not cover how to add mods to the default launcher. You can find our guide on doing so here.

How to download mods

You need to get the mods from CurseForge or the mod author's official site. Doing this ensures that you won't get corrupted files or viruses.
Once you decide on a mod you want, click the name to open the mod page.
Open the Files tab to view the versions. To the right of the version you want, press download. It's best to download the latest recommended update for your version of Minecraft.
Head back to the mods page and open the Relations tab. This is very important as these are the mods you need for it to work correctly. If you don't download the dependencies, the mod will not function properly or can cause the game to crash.

Common Issues

Minecraft Crashes on startup

When adding a mod to an existing modpack, it is very important that you check to make sure you are not missing any dependency mods. If you are, it can cause your game to crash upon loading.

Getting Mod Rejections when trying to join a server

Having a mod rejection either means that the mod is not the same version as the one from the server, or that you are missing a mod on your Minecraft client that is on your server or vice versa. Double-check that your mods folder from client-side matches with the server-side mods folder. Although, keep in mind that you do not need to add client-side only mods to the server. For example, Optifine needs to stay only on your Minecraft client, it does not go onto the server.
