For the server

Port 25565
Open on router
🟢
Modrinth App — Server
Easiest method — one-click server from the Modrinth launcher
1
Open the Modrinth App and find the pack
In the Modrinth App, navigate to your installed Craft and Conquer profile.
2
Click the three dots → Create Server
The app will generate a server folder pre-loaded with the correct mods and configs. Choose where to save it.
3
Accept the EULA
Open
eula.txt in the server folder and change eula=false to eula=true.4
Run the server
Double-click
start.bat (Windows) or run ./start.sh (Mac/Linux). The server will start on port 25565.💡 Share your local IP (from
ipconfig on Windows) with friends on the same network, or your public IP for external connections.🔧
Manual Server Setup
Full control — for experienced users or dedicated servers
1
Download Fabric Server
Go to fabricmc.net/use/server and download the Fabric server jar for Minecraft 1.21.11. Place it in a new folder.
2
Download the modpack mods
Download the Craft and Conquer modpack ZIP from Modrinth. Extract it and copy the
mods and config folders into your server folder.⚠️ Remove any client-only mods such as Drippy Loading Screen, Simple Menus, and LambDynamicLights from the server mods folder — they will crash a dedicated server.
3
Create a start script
Create a
start.bat file (Windows) with the following:java -Xmx6G -Xms2G -jar fabric-server-launch.jar nogui
pause
pause
4
Accept the EULA and launch
Run the start script once — it will generate files and stop. Open
eula.txt, set eula=true, then run again to fully start the server.5
Forward port 25565
In your router settings, forward TCP/UDP port 25565 to your server machine's local IP. Friends can then connect using your public IP.
💡 Use whatismyip.com to find your public IP to share with friends.

Paid Server Hosting
Best for always-on servers without running your own machine
If you want a server that stays online 24/7 without leaving your PC running, a server host is the way to go. These providers support Fabric modpacks:
Bisect Hosting
Easy one-click modpack installs. Good for beginners.
Apex Hosting
Solid performance, supports Modrinth packs directly.
Bloom Host
High performance, great for larger player counts.
💡 When setting up with a host, choose Fabric 1.21.11 as the server type, then upload the mods and config folders from the modpack ZIP.
Common Questions
Server FAQ
Do all players need the modpack installed? ▼
Yes. Every player connecting to the server needs the same version of Craft and Conquer installed on their client. They can download it from Modrinth or CurseForge (pending).
How many players can the server handle? ▼
With 6–8 GB of RAM allocated, the server should comfortably handle 4–8 players. For larger groups, consider a dedicated hosting provider with more resources.
The server crashes on startup — what do I do? ▼
The most common cause is client-only mods in the server folder. Remove Drippy Loading Screen, Simple Menus, and LambDynamicLights from the mods folder and try again. If it still crashes, post your error log in the Discord.
Can I use a different world seed? ▼
Yes — open
server.properties and set level-seed=YOUR_SEED before the first launch. You can also change the world name here.
