Check if your Insurgency: Sandstorm server is online
Insurgency: Sandstorm has a query port separate from the game port, and it is easy to miss because the default is not next to it.
The ports Insurgency: Sandstorm uses
Both are UDP, and the server browser and this tool read the query port. Sandstorm also has an RCON port that should never be open to the internet — this tool declines to test ports in the ranges administrative services usually use.
Every port a default Insurgency: Sandstorm install uses
With the game port left at 27102. If you changed it with -Port=, the other ports move with it.
| Port | What it is for |
|---|---|
| 27102 UDP | Game trafficRequired Port. |
| 27131 UDP | Steam queryRequired QueryPort, a separate fixed default rather than an offset. |
| 27015 TCP | RCONDo not forward Administrative console. |
Still offline? Try this
Set up UDP rules for both the game and the query port, then run the check again. A server that answers here yet is absent from the browser most likely lacks a valid login token, which listing requires in addition to reachability.
