Error code 271 means the experience kicked you out of the game. It is usually the game's own scripts, an admin action, or a server hiccup during play or while moving between places in the same game, rather than a problem with your account or connection.
If one specific game kicks you with 271 every time you join, read that game's rules or group page, since some games kick players automatically for failing a check, such as an age or account-age requirement. If every game kicks you the same way, reinstall Roblox and check your connection, since a corrupted install or an unstable connection can look like repeated kicks.
Is error code 271 a ban? No. A 271 is a kick from one experience, not an account ban. A ban would show a different message and block the account across Roblox.
Why was I kicked if I did nothing wrong? Games can kick players automatically for server errors, failed teleports, or script checks that misfire, and admins can kick for breaking that game's rules. The message does not say which one it was.
What is the difference between error 271 and error 267? Error 267 is a kick with a reason message set by the game's developer, while 271 is a plain kick from the experience, often from a server or teleport problem. Both end the session in the same way.
