Fix Sea of Thieves Error Code Marblebeard
These are some of the potential fixes reported by players around the world, try as many as possible until you get rid of this pesky error code.
Check Official Server status
Before pursuing any other potential solutions, you should first determine whether the problem is widespread or only occurs locally. It’s possible that the Sea of Thieves MarbleBeard Error is caused by a server issue that prevents you from connecting/reconnecting to a server.
Reset or Restart Router
You may be experiencing an IP / TCP networking inconsistency, which can be resolved with a simple router reset or restart.
Some users who were previously experiencing the same issue have confirmed that the issue has been resolved after forcing a router reboot or reset.
Begin with a simple router reboot to avoid overriding any previously established custom network settings. To restart your router, press the dedicated power button on the back or unplug the power cable from your networking device. After that, wait a full minute before powering on the router again.
Set NAT to Open or Enable UPnP
As many players have discovered, problems with Network Address Translation (NAT) are the most common cause of the Marblebeard Error. The game’s connection mechanism relies heavily on NAT. It must be active in order for the game to connect you to other players.
Enabling UPnP on your PC will solve the problem.
Manually Port-Forward
Regrettably, some routers were manufactured prior to the introduction of Universal Plug and Play technology. If you’re using an old router, it’s not automatically detecting and opening the game’s ports, which means it’s obstructing the connection process. In this case, you must manually forward the ports of the Sea of Thieves.
To find out how to forward specific ports, go to the router’s manufacturer’s support page. Keep in mind that the port you’ll be forwarding for Sea of Thieves is 3074.
