Question 1

Why do people have connection trouble with Satisfactory servers?

Accepted Answer

The most common cause is that a Satisfactory dedicated server needs two ports open, not one: the standard game port (default 7777, TCP+UDP) and the Reliable Messaging port (default 8888, TCP). This has been required since Update 1.1 and continues in 1.2. Self-hosted servers that only forward one port fail to connect reliably. We open and configure both automatically, so this is not something you need to manage.

Question 2

Is Space-Node's Satisfactory hosting updated for Update 1.2?

Accepted Answer

Yes, our servers run the current Satisfactory branch, including Update 1.2's weather system, fluid trucks, real pause, and the new Game Modes menu.

Question 3

How much RAM does a Satisfactory server need?

Accepted Answer

Early game with a small crew runs comfortably on 8GB. A growing factory with more automation and more players is more comfortable on 12GB, and a sprawling mega factory with a full crew benefits from 16GB.

Question 4

Can I upload my existing save to a dedicated server?

Accepted Answer

Yes. Upload your local or LAN save file through the panel and continue building on the dedicated server without starting over.

Question 5

Which regions can I host in?

Accepted Answer

Netherlands, Germany, Poland, Canada, USA (California), USA (Virginia), Singapore, India, and Australia. Pick the region closest to most of your crew, and check the live latency preview before you order.

Question 6

Is DDoS protection included?

Accepted Answer

Yes, on every Satisfactory plan at no extra cost.

Question 7

Why do players time out when joining my Satisfactory server?

Accepted Answer

Satisfactory needs two UDP ports rather than one: a query port and a game port. If only one is reachable, the server appears in the list but joining fails or times out. This has been the case since version 1.1, and it catches people who set up a server before that.

Question 8

How much RAM does a Satisfactory server need?

Accepted Answer

Satisfactory memory use scales with factory size, not player count. An early game save is fine on 6GB. A late game megabase with thousands of belts, machines and trains regularly needs 12GB or more, and it will keep climbing as the factory grows.

Question 9

Does the server keep running when nobody is playing?

Accepted Answer

A dedicated server keeps simulating the factory whether or not anyone is connected, which is the entire point of running one. Production continues, trains keep moving, and you come back to full containers rather than a paused world.

Question 10

Can I upload a save from a solo game?

Accepted Answer

Yes. Satisfactory saves transfer cleanly from single player to a dedicated server, so you can start solo and move the factory across once your group grows.

Question 11

Why does my factory tick slower as it grows?

Accepted Answer

Belt and machine simulation is CPU bound and largely single threaded, so a very large factory is limited by single core speed rather than by core count. This is why per core performance matters more than thread count for Satisfactory specifically.

Question 12

What is the "Outgoing reliable buffer overflow" error?

Accepted Answer

The server is trying to send a client more state than the connection can carry, usually when joining into a very large factory. It is a symptom of factory size and connection quality rather than of a broken server, and it tends to appear on the initial join rather than during play.
