How to Install Minecraft Modpacks on the SkailarHost Game Panel
Installing modpacks on SkailarHost is built into the panel: you choose a pack, select a version (Forge/Fabric/etc.), and the panel installs the correct server files for you. This guide shows the fastest “clean install” method and the most common fixes if the pack won’t boot.
TL;DR
Stop your server → open Modpacks → select a pack + version → enable Delete existing files for a clean install → click Install Modpack → start server and wait for the first boot.
Step 0 — Stop the server (recommended)
If your server is currently running, stop it before installing a modpack. This prevents file locks and avoids partial overwrites during installation.
Quick checklist:
- Server status: Offline
- No update/install task running
- You know if you want to keep existing worlds
Step 1 — Open the Modpacks tab in the panel
In your server’s left sidebar, go to Management → Modpacks. This is where you can browse and install supported packs directly from the panel.
Tip: choose the right pack type
Many packs have multiple variants (Forge vs Fabric). Always match the version shown in the modpack selection dropdown to what you want players to run.
Step 2 — Select a modpack and version
Click a modpack (example: “Cobblemon Adventure”), then use the version dropdown to choose the pack version you want. The panel will install the correct server files for that exact release.
Step 3 — Decide if you want a clean install
You’ll see a toggle like Delete existing files. This controls whether the panel wipes your current server directory before installing the pack.
What to choose:
- ON (recommended) → clean install, best when switching packs or fixing broken files.
- OFF → attempts to install alongside existing files (use only if you know what you’re doing).
Important: Worlds & Backups
If you enable deletion, your current world can be removed. Take a Backup first if you want to keep it (Backups → Create Backup).
Step 4 — Install, then wait for it to finish
Click Install Modpack. The panel will download files, configure the loader, and prepare the server directory. Don’t restart mid-install.
What “normal” looks like:
- Download/extract step may take a few minutes
- Files appear in the Files tab after completion
- First boot after install usually takes longer
Step 5 — Start the server and verify modpack boot
Start your server and watch the console. On first launch, many packs generate configs, download dependencies, or create initial world data.
Tip: give the first boot time
If it looks “stuck” but memory/CPU is moving, wait a bit. Modpacks can take longer than vanilla Minecraft on first start.
Common issues (and quick fixes)
1) “Wrong loader” (Forge vs Fabric)
If you picked a Fabric pack but your server is running a Forge setup (or the opposite), it may crash instantly. Fix it by reinstalling the modpack and selecting the correct pack version/loader in the dropdown.
2) Not enough RAM / out of memory
Bigger packs need more memory. Symptoms include crash loops, “GC overhead,” or “OutOfMemoryError”. Increase RAM directly from your client area or use a lighter modpack.
3) Server installs but won’t start
Most often it’s one of these: Java version mismatch, pack requires a newer Minecraft version, or a corrupted install. Try a clean reinstall with Delete existing files enabled (after making a backup).
4) Clients can’t join (“incompatible mod list”)
Players must use the exact same modpack version as the server. Share the modpack name + version with your players, and avoid mixing “extra mods” unless everyone has them.
