How do I check if my Rust server is online?
Enter the address players use, including the game port. We query it from the public internet the way the server browser does, so a green result means players can see it.
What is the Rust server query port?
By Facepunch's rule it is one more than the higher of server.port and rcon.port, which is 28017 with the defaults of 28015 and 28016. You can set it yourself with +server.queryport.
Why is my Rust server not showing in the server list?
The usual causes are a closed UDP query port, a server that is still loading, or a query port that moved because you changed server.port or rcon.port.
Can I be alerted when my Rust server goes down?
Yes. ServerStats basic mode checks the same query around the clock, keeps player history across wipes and posts to Discord when the server stops answering. Free for one server; the Rust plugin adds server FPS, entities and wipe analytics.
