How to Join Your IOSoccer Server

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

Note

You can find the IP address and the Game Port of your server in the dashboard of your server. IOSoccer uses the same port for gameplay and for server queries — there is no separate Query Port.

Warning

Always enter the Game Port from the dashboard. Port 27005 is the local client port of your game and must not be used as a server address.

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

   Example

   connect 123.45.67.89:27015

   Use the IP address and the Game Port from your dashboard here.

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

Tip

You can also reach your server directly through Steam. Enter the following address in your browser or in the Windows Run dialog — Steam launches the game and connects you automatically:

steam://connect/123.45.67.89:27015

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.

Note

By default the Internet tab of the server browser hides servers that run a different game version. If your server does not show up there even though it is running, first check whether server and game are on the same version. You can still reach it through the direct connection.

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

Note

You do not need a Steam Game Server Login Token (GSLT) for IOSoccer — the server does not support login tokens because it runs on an older branch of the Source Engine. With sv_lan 0 it registers with the Steam master servers without a token. If it ever fails to register in time, trigger the registration again with heartbeat in the server console.

Tip

After changing the server.cfg you have to restart your server for the values to be applied.

Which ports does IOSoccer use?

Note

Port	Purpose
Game Port	Gameplay, server queries and RCON — this is the port you enter when joining
Client port 27005	Local port on the player's PC, not a server address
SourceTV port	Only relevant if you use SourceTV for spectators

You can see the values that apply to your server in the dashboard.
