How to Host an ATM8 Server
Hosting All the Mods 8 cleanly is less about some hidden command and more about doing the obvious things in the right order: enough RAM, a proper modpack flow, a clean first boot and backups before you get adventurous with 350+ mods.
Start with 10 GB unless this is a very small server — ATM8's own recommended floor, not a generic guess.
Use a proper modpack import flow instead of guessing from a client export.
Watch the first boot logs until every mod finishes loading — a 350+ mod pack takes real time on first boot.
Invite players only after the first clean startup.
Take a backup before world imports, Forge updates or config changes.
Use a cleaner ATM8 path
CoalHost is built around modpack hosting, which makes a 350+ mod pack like ATM8 much less annoying to launch correctly.
