Hytale updated and nobody can join

Hytale versions look like a date plus a code, for example 2026.01.22-6f8bdbdc4, and game and server must match exactly. The launcher updates the game on its own, so right after a patch your friends are on the new version while your running server is still on the old one. Until the server restarts, every join fails. This is true on every host, and for self-hosted servers too.

The error wording changes between patches, so don't go by the message. If joins started failing right after a Hytale update, treat it as a version mismatch first.

Press and hold Restart on your server card until the ring completes. During startup the server pulls the newest build on its own: nothing for you to download, no reinstall, and your worlds, characters, and settings stay exactly as you left them. The first start after a large update can take a few extra minutes while the new files come down.

The update lands on any start, not just a restart, so a server that was stopped or sleeping comes back already on the latest build.

Hytale servers don't show an update warning on the card yet, so the version itself is your check: your server card shows the game name and the running version, just above the address strip. After the restart it should read the newer date.

If the version didn't change and the Hytale patch is only an hour or two old, the new server build is probably still rolling out. Wait a bit and restart again.

If everyone got back in except one person, the mismatch is on their side.

• Their game hasn't updated yet. Have them fully close Hytale and the Hytale Launcher, reopen the launcher, and let it finish updating before launching the game.

• They're on the pre-release branch. Hytale tests upcoming updates on an opt-in pre-release branch in the launcher. Pre-release clients run a different version and cannot join stable servers. They need to switch back to the regular release. There is no pre-release option for Haptic servers.

Matching versions is a Hytale rule, not something we control, so no server setting will let an outdated or pre-release player in.

After a game update, an outdated mod is the next most common reason a Hytale server won't start or won't accept players; mod authors need time to catch up after each patch. Turn that mod's Enabled switch off in the Mods card until the author ships a fix, then restart: see mod load order and on/off toggles. Your players install nothing either way, because Hytale mods are server-side.

Auto Restart (in your server's expanded Overview settings, under Basic) doubles as set-and-forget updating. New servers come with it set to Every 48 hours. Switch it to Every 24 hours (daily), then click Save changes in the save popup: the dropdown alone doesn't stick if you navigate away. Your server then picks up new builds on its own, usually within a day. Scheduled restarts back the server up first and wait until the world has been empty for 15 minutes, so a busy server can run past its scheduled time. Details in automatic server restarts.

Hytale servers on Haptic always track the latest stable release: there is no version dropdown and no way to pin an older build. Backups protect your worlds, not the game files, so restoring a backup won't put the server back on an older patch either.
