Sea of Thieves Server Status

You’ve probably noticed that the Sea of Thieves servers were chaotic on launch day, with several bugs occurring in players around the world. As Sea of Thieves is a game where you have to be online all the time to be able to play, the status of the servers is of utmost importance for the game.

If you need to check the status of the servers in the pirate adventure game Rare, visit the Sea of Thieves server status page.

Make sure the NAT is OPEN

It turns out that the most common problem that causes the MarbleBeard Sea of Thieves error on the Xbox One and the PC is the inconsistency with the Network Address Translation (NAT). This is absolutely necessary to determine how easily your computer can connect to other players when you play a game.

If your NAT is closed, you can expect to see the Marblebeard error code every time you try to connect to a game server.

However, there is a universal patch (enable UPnP) that allows you to leave your NAT open. But before you get to this guide, you should check the status of your NAT.

If your NAT is already open, activating UPnP (Universal Plug and Play) will not solve the problem for you.
