If you can’t connect to your Satisfactory dedicated server, first check the server is fully started, then add it in the in-game Server Manager with your IP and port 7777 and join from there, not with Join Game. The server must have a game created or loaded, and your game must run the same version and branch. “Encryption token missing” means the player didn’t join through the Server Manager.

​
Before you start

  • Find your server address on Overview or Network in the Game Panel, for example 203.0.113.10:7777.
  • Open the console so you can see what the server is doing.

​
Step-by-step fixes

1

Check the server is ready

The console must show Server API listening on '0.0.0.0:7777' and Server streaming socket bound to port 8888. On the very first start the server downloads about 1.5 GB first, which takes several minutes.
2

Add the server in the Server Manager

In Satisfactory, open Server Manager > Add Server, enter the IP and port 7777. Don’t use Join Game from the main menu for a dedicated server.
3

Accept the certificate

The server uses a self-signed certificate, so a Server Certificate Warning appears the first time. Click Confirm.
4

Make sure a game is running

A new server has no game. The admin has to create one in Create Game or load one in Manage Saves before anyone can join. See getting started.
5

Match the version

Update your game. If the server runs Experimental in Game settings > Game branch, players need the experimental branch too; see experimental branch.
6

Match mods

On a modded server, every player needs the same mods and versions. See install mods.

​
Certificate errors

The certificate warning on first connect is expected, and the console prints Server API is running using a Self-Signed Certificate at every start. If the game says the certificate is “not yet valid”, the clock on your PC is probably wrong: set the date, time and time zone automatically and try again. If the server’s certificate changed (for example after you reset the admin password by deleting ServerSettings.7777.sav), remove the server from your Server Manager and add it again.

​
Players time out while loading

On a big world, slow PCs or connections can take longer than the server allows. On Game settings, apply the Patient connections preset (“Longer timeouts for players with slow connections”) or raise Time to connect (30 seconds on a new server), save and restart.

​
Frequently asked questions

​
Why isn’t my Satisfactory server in a server list?

Satisfactory has no public server browser. Every player adds the server by address in the Server Manager.

​
Which port do I enter?

7777. The reliable messaging port 8888 is found by the game automatically. See server ports.

​
Do I need the player password to connect?

Only if the admin set one under Player Password Protection. Ask the admin, or see admin management.

​
How do I connect with an IPv6 address?

Put the address in square brackets, for example [2001:db8::10], or use your IPv4 address.

​
It still doesn’t work. What should I send support?

The error message, the time it happened and the last lines of FactoryGame/Saved/Logs/FactoryGame.log. Open a ticket.
