Rare names this code but does not publish the wording it prints on screen, so we quote only the code itself: Kiwibeard. Any site showing you an exact message for it has written one.
This one genuinely goes both ways, so the first job is telling which you are looking at.
Rare reports Sea of Thieves services healthy
Rare lists two causes and only two. The first: “The Servers Are Closed – We are not running a play session when you tried to log in, so you cannot play Sea of Thieves right now.” The second: “You have more than one Gamertag signed in to your console.”
Historically this code is associated with playtest and Insider sessions, where access is scheduled rather than continuous.
Sign every account out of the console except the one that owns the game, then launch again. If Kiwibeard persists with a single account signed in, the servers are closed and you are done for now.
Operator documentation: support.seaofthieves.com. Rare documents every beard code in one catalogue, last updated 22 May 2025, and that catalogue states its own completeness. It describes causes and fixes but never quotes the message the game prints, which is why this page does not either.

Start with: Sign out every other account. Rare's wording is explicit: sign all other accounts out of the console and launch with only the one invited to play. This is the half of the problem you can actually solve.
