# Satisfactory Server Ports: 7777 TCP/UDP and 8888 TCP

> Satisfactory dedicated servers use port 7777 TCP and UDP for the game and Server API, and 8888 TCP for reliable messaging since 1.1. 15777 is gone.

A Satisfactory dedicated server uses two ports: 7777 over TCP and UDP for game traffic and the HTTPS Server API, and 8888 over TCP for reliable messaging, which is required since version 1.1. Ports 15000 and 15777 are no longer used since 1.0. On FREAKHOSTING both ports are already set up; players connect with your address and port 7777 only.

| Port | Protocol | Used for |
| - | - | - |
| 7777 | TCP and UDP | Game traffic and the HTTPS Server API (Server Manager) |
| 8888 | TCP | Reliable messaging, required since 1.1 |
| 15000, 15777 | – | No longer used since 1.0 |

## Which ports does my FREAKHOSTING server use?

Open **Network** in the [Game Panel](https://games.freakhosting.com) to see your allocations. Your server has port 7777 for the game and Server API, and 8888 for reliable messaging. The **Startup** page shows them in the command line as `-Port=7777 -ReliablePort=8888`. **Reliable Port** on the **Startup** page is read-only and described as "Reliable messaging port. Required for version 1.1 or above."

## Which port do players enter?

Only the game port. In the Server Manager, click **Add Server**, enter your IP, for example `203.0.113.10`, and port `7777`. The game finds the reliable messaging port by itself.

## How to check that both ports are open

**1. Start the server**

Start the server and open the [console](https://help.freakhosting.com/portals/game-panel/how-to-use-the-server-console.md).

**2. Look for the two ready lines**

`Server API listening on '0.0.0.0:7777'` shows the game port is open. `Server streaming socket bound to port 8888` shows the reliable messaging port is open.

**3. Connect**

Add the server in the Server Manager with port `7777`. If it fails, see [connection problems](https://help.freakhosting.com/games/satisfactory/satisfactory-server-connection-problems.md).

## Frequently asked questions

### Do I still need ports 15000 and 15777?

No. Satisfactory stopped using them in version 1.0. Guides that mention them are out of date.

### Why does my server need port 8888?

Since Satisfactory 1.1 the server uses a second TCP port for reliable messaging, and it must be reachable alongside 7777. On your server it is already allocated.

### Can I change my server's ports?

The ports come from your server's allocations and are set for you. If you need a different port, [open a ticket](https://freakhosting.com/clientarea/submitticket.php).

### Is port 7777 TCP or UDP?

Both. Port 7777 must be open for TCP and UDP. It carries game traffic and the HTTPS Server API that the Server Manager talks to.
