Issue
Tried to add a cursedforge modpack “Dungeons Dragons and Spaceshuttles”
Following a guide, from HostingerAcademy
Created the Mods folder
Added the forge 1.12.2 Zip into the mods folder
Added the Server zip for the modpack into the mods folder.
Unable to start
Given the error:
The Minecraft server stopped within 5 seconds of starting, this is not a fault with AMP - you should check your Minecraft servers log files to find out why it is unable to start.
Reproduction Steps
- Created the Mods folder
- Added the forge 1.12.2 Zip into the mods folder
- Added the Server zip for the modpack into the mods folder.
- Configured Instance to Forge 1.12.2
