What we ask the server
Valheim answers Steam's A2S query over UDP on the game port plus one: 2457 when the game runs on 2456.
Valheim server status checker
See whether a public Valheim dedicated server answers the Steam query from the internet, with response time and player count when available.
Checked from our server on the public internet. We don't store the addresses you check or any player names. Private and local addresses are refused.
How the Valheim check works
It must be public
The query socket only answers when the server is started with -public 1. With -public 0 it never replies, so it shows as offline here.
Crossplay servers
The basic info reply may say 0 players while occupied. We use a positive anonymous player-list count when available; otherwise player count stays unknown. Names are not shown.
Valheim server showing offline? Check these
- The server runs with
-public 0, so it doesn't answer queries. - UDP 2457 (game port + 1) is closed. Valheim needs both the game port and the next one open.
- You entered the query port instead of the game port. Enter the port players use; we add one.

Questions
What is the Valheim query port?
The game port plus one: 2457 with the default 2456.
Why is my Valheim player count unknown?
Crossplay may report 0 in the basic info query even while occupied. If the anonymous player-list query supplies no positive count, we cannot verify the count; the server status and ping still work.
Can I get alerts when my Valheim server goes down?
Yes. ServerStats basic mode checks it continuously and posts to Discord when it stops answering. The Valheim mod adds deeper data.
Watch it around the clock, free
Basic mode runs this check continuously for one server, keeps the history and alerts you in Discord when it goes down.
