If you are getting the ‘anteater’ error code while trying to play Bungie’s extraction shooter, Marathon, with an additional message saying, “lost connection to the game world,” I’ve got you covered with this guide.
After Bungie’s Destiny games, the error codes like Currant, Weasel, Marionberry, Banjo, etc., have made a return in their new IP, Marathon, including the infamous ‘anteater’ error code.
Whenever players encounter this error, they are forced back to the login screen with a big black and red screen with the error code and additional messages.
But what is this ‘anteater’ error, and how to fix it?
What is the anteater error in Marathon?

Just like error code ‘Currant,’ the ‘anteater’ is a networking error that arises whenever your game client is unable to establish a connection with Marathon’s game servers.

How to fix the anteater error

First of all, before we proceed with the troubleshooting steps, make sure to check the current server status for Marathon.
If the servers are up and running, try out the steps below.:
Restarting your game

As trivial as it sounds, it is a Bungie-recommended step, and so, you must restart your game whenever you encounter the ‘anteater’ error.
If you are still facing the issue, follow the below troubleshooting:
Modem + Router = Issues
Most of the commercial cable modems that we use have a router with wifi functionality attached to it, which leads to an unstable internet connection, which, as per Bungie, often causes different network issues while playing their games, including Marathon.
To fix this, it is recommended to disable the router functionality, as a Cable connection is a way better option than the wireless one.
Check your modem/router manual and set it to “Bridge” mode, which in some cases may also be called “NAT Disabled” mode.
Double NAT Type
Double NAT Type occurs when your system and Marathon or any game report a different NAT Type.
To fix this, you must set your modem/router in “Bridge” mode or “NAT Disabled” mode.
Cable Modem Resets
Most of the modems restart automatically whenever they encounter an error that exceeds a certain threshold, commonly known as the “error rate reset threshold.”
While a regular user never reaches the threshold, if the issue is from the ISP’s end, it could lead to a network error in Marathon, too.
So contact your ISP and double-check if everything is looking fine from their end.
That sums up everything you need to know about the anteater error code and how to fix it in Marathon. There are some additional basic troubleshooting steps, like restarting your modem/router, checking the firewall to ensure Marathon is not blocked, etc.
