Troubleshooting
Quick fixes for the most common issues.
"Room not found"
Double-check the 4-letter code. Codes use only unambiguous characters, so there is no O vs 0 confusion. If the host closed the room, a new code is generated.
"Host not connected"
The big screen must stay open and connected. Refresh the host page and wait for it to show the room code before joining.
Controller stuck on "Joining…"
Some browsers block the real-time connection. Retry the join, or use a different browser. The join screen always reappears so you can try again.
Changes not showing
A stale server may be holding the port. Restart the server so the latest build is served, then reload the host page.
Still stuck? Check the host screen first — it always shows the current room code and connected players.
