Question 1

How do I install tModLoader on my Terraria server?

Accepted Answer

Select tModLoader from the panel's installer, it swaps your server over without losing your existing world. From there, add mods individually or install a full Steam Workshop modpack collection.

Question 2

Can I run a heavy modpack like Calamity?

Accepted Answer

Yes. Calamity, Thorium, and other large overhaul modpacks run fine on our Medium tier for most groups, and the Large tier gives more headroom if you stack multiple big modpacks together with more players.

Question 3

How much RAM does a Terraria server need?

Accepted Answer

Vanilla Terraria or a light modpack runs comfortably on 2GB. A real tModLoader modpack like Calamity is more comfortable on 4GB, and stacking multiple heavy overhaul mods with more players benefits from 6GB.

Question 4

Can I switch between vanilla and modded without losing my world?

Accepted Answer

Yes, switching the server type through the panel does not delete your world files, though some mod content may not display correctly if you load a modded world without the matching mods installed.

Question 5

Which regions can I host in?

Accepted Answer

Netherlands, North America, Singapore, and India. Pick the region closest to most of your players, and check the live latency preview before you order.

Question 6

Is DDoS protection included?

Accepted Answer

Yes, on every Terraria plan at no extra cost.

Question 7

Should I run vanilla Terraria or tModLoader?

Accepted Answer

Vanilla if you want the base game and the smoothest multiplayer. tModLoader if you want mods, but be aware that it tracks its own version of Terraria and often lags behind an official update, so a fresh Terraria patch does not immediately mean a working modded server.

Question 8

How much RAM does a Terraria server need?

Accepted Answer

Terraria is light by modern standards. A vanilla server for a handful of friends runs comfortably on 2GB. Large worlds and heavy tModLoader mod lists are where memory use climbs, and a big modded server is happier with 4GB or more.

Question 9

Can Steam and mobile or console players join the same server?

Accepted Answer

No. Terraria dedicated servers are for the PC version. Console and mobile use their own multiplayer and cannot connect to a PC dedicated server.

Question 10

How do I move an existing world to a server?

Accepted Answer

Upload the .wld file to the worlds folder and point the server config at it. Take the .bak alongside it as well, because Terraria writes a backup on every save and it is the fastest recovery if a world file gets damaged.

Question 11

Why do players get kicked when a boss spawns?

Accepted Answer

Usually a spike in entity updates on a connection that cannot keep up, rather than a server fault. Large events like a Martian invasion or a boss fight with many summons generate far more traffic than normal play.

Question 12

Do mods need to be installed by every player?

Accepted Answer

For tModLoader, yes. Every player needs the same mod list at the same versions. tModLoader can serve mods to joining clients, but matching versions is still the thing that decides whether a join works.
