Applies to builds from 1.0 to 1.0.15 (11 Nov 2026). Each step names the patch or announcement it comes from. None of these checks touch your save files.

1. Make sure everyone is on the same version

Since patch 1.0.10, the room list only shows rooms that match your game version by default. If the versions differ, the game tells you whether you or the host needs to update. Many connection fixes also landed between 1.0.10 and 1.0.15, so an outdated client can show problems that are already fixed.

NoteUpdate through Steam and fully restart the game on every machine, host included. The host should back up the world first; see the backup guide.

2. Search for the code instead of scrolling the list

You can type the 6-digit room code straight into the room list’s search box (patch 1.0.10). If you are browsing instead, check the Hide locked rooms and Hide full rooms filters added in patch 1.0.4: a password-protected or full room is hidden while they are on.

NoteRooms you have joined before are pinned at the top of the list, including private rooms, and your last password is remembered (patch 1.0.11).

3. The digits do not appear when you type the code

The developer confirmed this is a display bug: the code is entered, but the numbers do not show in the field. Type the six digits as normal and press Join. If the room has a password, enter it in the password field first, then press Join.

NoteThe developer announced a fix for patch 1.0.8. If you still see this on a newer build, report it through the in-game Feedback Center.

4. You get “Wrong password” without entering one

Before patch 1.0.10, joining a password-protected room with an empty password field showed “Wrong password”. Since 1.0.10, the game asks you for the password instead.

NoteAsk the host for the password before joining, and type it before pressing Join.

5. The host never receives a room code

Since patch 1.0.12, if no room code arrives within 20 seconds of hosting, the game shows the likely cause and keeps retrying on its own. The causes it names are packet loss on the network, or a network accelerator or security software blocking the connection. LAN and direct connections are not affected.

NoteTurn off a network accelerator first, since that is the easiest cause to rule out. Check your security software’s log for a blocked connection before changing any rule, and never disable protection entirely.

6. Still stuck: join another way

A room code is one of four ways in. The launch announcement also lists the public room list, Steam friend invites and LAN. When a direct connection is not possible, the game falls back to the official relay server automatically, and patch 1.0.13 improved the success rate of direct connections.

NoteIf nothing works, report it through the in-game Feedback Center or the official Discord with your game version and which of these steps you tried.
