DayZ 1.30 Stable Steam Server Not Showing Up in the Built-In Server Browser or the Launcher

### Steps to Reproduce

1. Install a DayZ 1.30 Stable Windows server using Steam.

2. Open UDP ports 2302–2305 and port 27016.

3. Include -port=2302 as a launch parameter.

4. Optionally, explicitly set steamQueryPort = 27016; in serverDZ.cfg.

5. Start the server and ask an external client to find it in the built-in server list or the built-in DayZ Launcher.

### Expected Result

The server appears in both the built-in server list and the built-in DayZ Launcher.

### Actual Result

The server does not appear in either the built-in server list or the built-in DayZ Launcher.

Question: Is there an undocumented or unlisted port required for the server to appear in the built-in server list and the built-in DayZ Launcher?
