Error 401 in Adopt Me usually means the code wasn’t recognized or can’t be redeemed. In practice, players commonly see it when a code is typed wrong, copied with extra spaces, or no longer exists.

What it means

In Roblox Adopt Me , “Error 401” is typically shown with a message like “Code not found! Please try again.” That points to an invalid or unrecognized code rather than a general account problem.

Common causes

  • The code was entered incorrectly, even by one character.
  • The code is not valid anymore or was never active.
  • There may be an authentication-style 401 issue in other apps, but in Adopt Me the code message specifically indicates the code could not be found.

What to try

  1. Re-enter the code exactly as shown, with no extra spaces.
  1. Copy and paste it instead of typing it manually.
  1. Check whether the code is expired or removed from the game.
  1. Restart the game and try again if the kiosk seems stuck.

Simple example

If a code says one thing but you type a similar-looking letter or number, Adopt Me may return Error 401 because the code does not match anything it recognizes.

TL;DR: In Adopt Me, Error 401 usually means “code not found” or entered incorrectly, not a ban or permanent account issue.
