How to join your Factorio server and set a password Print

This article explains how players can join your Factorio server hosted on PlayNHost, and how to set or change the server password.

1. Find your server IP and port

1. Log in to the Client Area at https://playnhost.com/billing.
2. Go to Services → My Services and open your Factorio server.
3. Note the IP / Hostname and Port shown on the Product Details page.
4. You can also see these values in the Game Panel at https://panel.playnhost.com on the server dashboard.

Give players the address in the format: IP:Port (for example, 123.45.67.89:34197).

2. Start your Factorio server

5. Go to https://panel.playnhost.com and log in.
6. Select your Factorio server.
7. Click Start and wait until the console shows that the server is running and has loaded a save.

3. Join the server from Factorio

8. Open Factorio on your PC.
9. From the main menu, click Multiplayer.
10. Click Connect to address (or similar option).
11. In the address field, enter your server address (for example, 123.45.67.89:34197).
12. Click Connect.
13. If the server requires a password, Factorio will prompt you to enter it.

4. Set or change your Factorio server password

Factorio server details (name, description, password, etc.) are controlled by a server-settings file or by a settings page in the panel.

• In the Game Panel, open File Manager for your Factorio server.
• Find the file called server-settings.json (usually in the root or a config folder).
• Click it to open the editor.
• Look for the line that sets the password, for example:

  "password": ""

• Set the value to the password you want:

  "password": "YourSecretPassword"

• Make sure the JSON formatting stays valid (quotes and commas in the right places).
• Click Save.

If your panel has a dedicated Server Settings page for Factorio, you may be able to set the password there instead. Use whichever method is available.

5. Restart the server to apply changes

14. Go back to the server dashboard.
15. Click Restart (or Stop then Start).
16. After the server is online again, players will be asked for the new password when they connect.

6. Troubleshooting connection problems

• “Could not establish connection” or timeout
  Confirm the server is running in the Game Panel, and that players are using the correct IP and port.
• Wrong password
  Double-check the value in server-settings.json or your settings page. Remember passwords are case-sensitive.
• Only some players can join
  Check that your player limit is high enough and that they are all using a compatible Factorio version/mod set.

If players still cannot join after checking these steps, please open a ticket from Support → Submit a Ticket and include your server IP, port, and any error messages players see.
