Do this first
The quick route
- Confirm the host is still inside an active hosted session.
- Have the host reopen the joining screen and send the code shown now.
- Retype the code carefully instead of copying spaces or punctuation.
- Make sure every player has installed the latest game update.
- Restart the host session once to generate another code, then retry.
Why an older code can fail
The official FAQ says a short, unique Join Code is generated every time the host starts a session. That makes the live code the first thing to verify after a restart, crash, update, or host change.
Separate a code issue from a session issue
If a same-platform friend can see and enter the active game from the friends-game menu, but the code fails for others, regenerate and re-enter the code. If nobody can see or join the game, treat it as a host-session or connection problem instead of repeatedly typing the same code.
When to stop retrying
There is not yet an official public error-code directory for Big Walk. If a fresh code, matching game versions, and a full restart do not help, record each platform, the exact on-screen wording, and the time of the attempt before contacting Panic support. That evidence is more useful than an undocumented network tweak.
