How to Join Your Factorio Server

Factorio does not have a Steam server browser for rented servers. Instead, you connect directly using the IP address and port of your server.

Find connection details

Important

To connect you need the IP address and the port of your server. You can find both in the dashboard of your server. Factorio only uses a single port over UDP (default: 34197) – there is no separate query port.

Via Connect to address

1. Start Factorio
   Launch Factorio on your PC.

2. Open Multiplayer
   Select Multiplayer in the main menu.

3. Select Connect to address
   Click on Connect to address.

4. Enter server address
   Enter the IP address and the port of your server, separated by a colon:

   Example

   123.45.67.89:34197

5. Connect
   Confirm your input. If a password is set on the server, you will be prompted for it afterwards.

Via the public server list

If your server is listed publicly, you can also find and join it via Multiplayer → Browse public games.

Note

For your server to appear there, you need valid factorio.com credentials. Enter them in the dashboard under Settings in the fields Server Benutzername and Server Token. The token is safer than the password and can be retrieved from your profile on factorio.com.

In addition, the visibility must be set to public in the file data/server-settings.json. You can edit the file via SFTP:

"visibility":
{
  "public": true
}

Afterwards, restart your server.

Warning

Do not enter username and token directly in the file data/server-settings.json. Both values are overwritten on every server start from the Server Benutzername and Server Token fields in the dashboard.

Important

Client and server must use the exact same game version and the same mods. Factorio verifies this by checksum and refuses the connection if anything differs.

Note

By default the option require_user_verification is enabled on a Factorio server. Players therefore need a valid factorio.com account in order to join.
