Frequently Asked Questions

Answers to the questions that don’t need a full page of their own. For anything more specific, use search or browse the sidebar — most topics here link to a longer page.

Do I need to keep my computer on?

No. This is the main difference between hosting and playing over a LAN world or “Open to LAN” — your server runs on AtomicHost’s hardware, not your PC, so it stays online whether or not you’re playing, or even signed in.

Do my friends need to do anything special to join?

No port forwarding, no VPN, nothing on their end. They just need your server’s address — see Connecting to Your Server — and, if you’ve turned on an allow-list, to be added to it first.

Can I move my existing single-player world to my server?

Yes. Zip your world folder (find it under .minecraft/saves/ on Java, or the world’s folder under Bedrock’s minecraftWorlds/), upload it through the panel’s Files tab, and set level-name in server.properties to match the folder name. Take a backup of the server’s current world first in case anything goes wrong.

Can I run mods and plugins together?

Not really, and not on the same server software — see Choosing Server Software for what’s actually compatible with what.

What happens to my world if I upgrade my plan?

Nothing — a plan upgrade changes your RAM/CPU allocation, not your files. Your world, plugins, and configs stay exactly as they are.

How do I change my server’s name or description?

There are two different “names,” and it’s easy to edit the wrong one:

• What players see in their server list — the server-name (Bedrock) or motd (Java) line in server.properties, editable from the panel’s Files tab. Changes apply on next restart.
• What you see in the AtomicHost panel — a separate, cosmetic label for your own organization, under Settings → Change Server Details (Server Name / Server Description). This is purely for you; players never see it.

Can I use a custom domain instead of an IP address?

Yes, if your DNS provider supports the record type your platform needs — an A record works for both. Point it at your server’s IP, then connect using the domain instead. A port number after the domain still applies the same as it would with a raw IP (see Connecting to Your Server).
