If this is your first time seeing this error, please try that activity again and resume what you were doing before encountering the error. If you encounter this a second time, please exit Marathon then relaunch the game.
If you repeatedly encounter this error, it likely means were testing something on our servers. Check out help.bungie.net and follow @BNGServerStatus for updates. If we are not currently running any publicized tests, please troubleshoot your connection by following the suggestions in our Network Troubleshooting Guide.
If you continue to encounter this error for an extended period of time, one final option to attempt a fix is to delete Marathon on your console and then reinstall Marathon. Please follow the links below to learn more about uninstalling and reinstalling Marathon.
If reinstallation does not improve your experience, it may be due to damaged or malfunctioning hardware. Check to see if other games work properly, or contact Customer Support for your platform for further information.
