You've typed "is Valheim down" into a search bar, which means someone can't get into a world tonight. Awkward truth: Valheim doesn't have game servers to be down. None. Every world lives on somebody's PC or on a dedicated server somebody rents, and Iron Gate run neither, so "Valheim is down" is never quite the diagnosis. There's no Valheim server status page to check, because there's nothing for one to report on. It's one of four things instead, and you can tell them apart in about two minutes if you check in the right order.
1. Steam is down
The most common one, and the one that looks most like the whole game being broken. Valheim on PC signs in through Steam, and a dedicated server without crossplay runs on the Steam backend, so the server browser, Steam favourites and the friends list all go down with it even though the server itself is running perfectly.
What it looks like: Steam itself is sluggish or offline, the server list is empty, friends show as offline when they're clearly not, or the game won't launch at all. Everyone. At the same moment.
Where to check: Valve doesn't run a proper status page, but https://store.steampowered.com/stats/ shows the live concurrent player count, and if that number has fallen off a cliff, that's your answer. The community-run https://steamstat.us/ breaks it down by service and is usually quicker to show trouble. Steam comes back on its own. Nothing to fix on the server.
2. The crossplay backend is having an outage
Since 1.0 shipped on 9 September 2026 a lot more servers run with crossplay on, because that's the only way PlayStation 5, Switch 2 and Xbox players get in. Crossplay moves the server off Steam's backend and onto Microsoft's PlayFab. That's where the six-digit join code comes from and what relays the traffic between platforms, and it's Iron Gate's own description of it, not mine.
PlayFab has bad days. Its official status page is https://status.playfab.com/, and it listed an increased failure rate across matchmaking, lobby and related APIs on 9 September 2026, which was launch day. Not the best timing.
What it looks like: join codes don't resolve, console players can't join, no join code appears in the server's output on start. Steam-only servers (crossplay off) are completely unaffected, which is the handy tell. On a crossplay server even the Steam players are stuck, because the IP they type is only a lookup key for the relay. Every crossplay server you know of dead at once, Steam-only ones fine? Look at PlayFab before you touch anything.
3. Valheim updated and your server didn't
This is where most of our "is Valheim down" tickets have come from since launch week. Valheim 1.0 arrived as 1.0.7, then 1.0.10 landed on 11 September, and 1.0.12 followed the same day on Steam. Three builds in three days. Steam updates the game on players' PCs automatically, but a dedicated server does not update itself, so the players come home, Steam has quietly patched their game, and the server is still sitting on last week's build refusing to talk to them. Restart it all you like. It stays on the build it had.
What it looks like: the server is online, the address is right, and you get an incompatible version message when you try to join, or the attempt just bounces you back to the menu. Every player, every platform, right after a Steam update. Check the version number in the corner of the main menu against what the server logged when it booted.
The fix is an update on the server side, then a restart. It's the one problem in this list you can actually solve yourself. There's a full walkthrough in the 1.0 update guide, and if mods are in the mix they need 1.0-compatible builds too, see Valheim mods after the 1.0 update.
One wrinkle. Switch 2 didn't get the 1.0.12 hotfix, so a 1.0.12 server can't be joined from Switch 2 right now, and Iron Gate's workaround is the default_old Steam branch. That mismatch isn't one you caused, and it isn't one you can fix by updating.
4. The specific server you play on is offline
If Steam is fine, PlayFab is fine and everyone is on the same version, the boring answer is usually the right one. The server is stopped, crashing on boot, or still loading. A Valheim world takes a minute or two after start before it accepts anyone, and the first boot after 1.0 takes longer still because it converts the old world files into the new folder format, so someone hammering Join in that window gets "failed to connect" and concludes the game is broken.
The other classic: the server started, then exited straight away because the password broke a rule. Five characters minimum, and it can't appear inside the world name or the seed. When it does, the server logs Error bad password: and quits. To a player, that's an outage.
Where to check on the LOW.MS panel
The triage above works for any Valheim dedicated server. If yours is with us, this is where each answer lives.
Is it up? The status sits right next to the Start, Stop and Restart controls at the top of the server page. Online or Offline. Offline with nobody having stopped it means it crashed or failed to boot, and the Console will say why.
Has it finished loading? The Console tab streams the server's output live, and the line that matters is Game server connected. Until it prints, nobody gets in. On a crossplay server the registered with join code NNNNNN line follows shortly after, and if that never appears, that's your PlayFab signal. A bad password shows up here too, right before the process exits.
Is it behind on the update? The Game updates card on the Overview tab tells you whether a newer build is waiting, with an Update button beside it. That's the whole fix for a version mismatch. I'd take a backup first out of habit. One button, Backups tab.
Still nothing? Then it's likely something specific to your world or your connection, and Valheim can't connect to server walks through those in order. Still dead at the end of that? Open a ticket from the panel and paste in the last screen of the Console, because that one paste saves us a round trip.
And if you're here because you host the world on your own PC and are tired of being the reason it's "down", that's what Valheim server hosting exists to fix. The world stays up when you don't.
