If you are on this site, you should experience the “Marblebeard” error when you try to connect with other friends. It’s a strange name for an error code that causes a kind of bitter boredom. However, don’t panic just yet because other gamers, including your fellow Xboxers, have also reported this error.

What is the cause of Sea of Thieves’ Marblebeard error code

What is the cause of Sea of Thieves' Marblebeard error code

  • Xbox Live server or game problem: The problem may be related to a server issue with the Xbox Live infrastructure or a general problem with game servers. In this case, there is no viable solution to fix the problem other than to wait or ask the developers to fix the problem.
  • Sea of Thieves port not being forwarded: Another common cause of this problem is the inability of the router to forward the port used by the game. If this is the case, you can solve the problem by enabling UPnP (if your router supports it) or by manually redirecting the game port (3074) in your router settings.
  • IP / TCP network incompatibility: It turns out that this problem can also be fed by a general network incompatibility, which does not allow the selected platform (Xbox One or PC) to establish a stable connection to the game server. In this case, restarting or rebooting the router should solve the problem.
  • Inconsistent MAC Address on Xbox One: If you see this error code on your Xbox One, the problem may be caused by an inconsistent MAC address that prevents your console from communicating with the game server. In this case, removing an alternate MAC address from the console’s network menu should solve the problem.
  • Corruption of system files: If this problem occurs only after an unexpected console shutdown or failed upgrade, it can be assumed that corruption of system files is causing connectivity problems. To fix this problem, perform a hardware reset on your Xbox One console.

Here's how to fix the Sea of Thieves Marblebeard error code

Reset Xbox One

  1. The Reset Console menu can be found under Settings – – Console Info.

  3. The rest of your game data can also be saved by selecting Rest and store my games and apps.
  4. The Marblebeard error may be gone after you reboot the console and reinstall and run the game.

Check if the NAT is open

On PCs or Xboxes, NAT (Network Address Translation) can be disabled, resulting in Marble errors.

  1. In the Guide menu, go to Settings -> All Settings on your Xbox One. Press the Xbox button on your controller and then click on the Guide button. To check if the NAT type status is open or not, select Network and click on Network Settings. The NAT type must be enabled if it is not enabled.
  2. If NAT on your computer is disabled, you may need to allow it or enable your router to enable it. You can check this status in Settings – > Games – > Network Xbox.
  3. You should also check your router settings. By default, your router allows NAT. However, sometimes you have to check, just in case. Launch your browser and type in the address of your router, for example `′ or `′, press Enter to open. Log in to your account and go to the Advanced menu, click the NAT Forwarding tab and make sure the UPnP option is enabled.
  4. A reboot of your Xbox, PC, and router will work if enabling NAT fails to resolve the issue.

Check the status of the Sea of Thieves server

The Sea of Thieves Marblebeard error code usually occurs when too many players are connected to a particular server, making the server slow and inaccessible to other users. If the server is under maintenance, you may encounter this error. If you have a slow internet connection, you may also encounter this problem.

A player’s internet connection or the game’s servers are likely to cause the said error.

Therefore, the first thing to do after finding the error is to check the status of the server. You can click on the link here and check if the server is down or inactive. You can also check other services, such as DownDetector, to confirm.

You can continue using the other methods if the servers are working well, but the error still occurs. But if the server is not working, you should wait until it is working well before connecting.

You can also check the server status on the Xbox Live status page. Although the game is built on the Xbox Live infrastructure, if there is a problem with the server, the game will stop working. If there is a problem with the server, none of the methods presented here can solve it. First make sure that the server is working properly, then apply the methods.
