How to Join Your IOSoccer Server

Join an IOSoccer server

3 min read
Jul 31, 2026

There are two ways onto your IOSoccer server: through the in-game server browser or through a direct connection using the developer console. There is no lobby system – joining via IP and port always works.

Find connection details

Enable the developer console in the game

You need the developer console for the direct connection. If it does not respond, enable it like this:

  1. Start IOSoccer
    Launch the game and wait for the main menu to load.

  2. Open the options
    Open the Options from the main menu and switch to the Keyboard tab.

  3. Open the advanced settings
    Click the Advanced button.

  4. Enable the console
    Tick Enable Developer Console and confirm the setting.

Connect through the game console

  1. Open the console
    Press ~ or ` in the game to open the console.

  2. Connect
    Enter the following command:

    connect IP:Port
    
  3. Reconnect
    If the connection drops, the command retry brings you back to the same server without typing the address again.

Via the in-game server browser

  1. Open the server browser
    Start IOSoccer and open the server browser in the main menu.

  2. Search for your server
    Switch to the Internet tab and search for the name of your server.

  3. Join
    Select your server and connect.

Via Steam favorites

If you cannot find your server in the list, add it directly in Steam.

  1. Open Steam
    Open the Steam client.

  2. Open the server browser
    Click on View in the top left and select Game Servers.

  3. Add the server
    Click on the Favorites tab and then on + at the bottom right.

  4. Enter the server address
    Enter the IP address and the Game Port of your server and confirm.

  5. Join
    Select the server and connect. The server then also appears in the favorites section of the in-game server browser.

Show the server in the public server list

Add these values via SFTP to the following file. If it does not exist yet, create it:

/iosoccer/cfg/server.cfg
Setting Meaning
sv_lan 0 Server is publicly reachable and logs in to Steam (1 = LAN only)
sv_region Region for the server browser (default value 255 = worldwide)
sv_tags Custom tags players can filter by in the server browser
