Unfortunately, it isn’t currently known what precisely is causing the error. Being relatively widespread, it’s likely that something is going awry with developer 343 Industries’ servers, as opposed to the issue being on the user end. That being said, there are troubleshooting steps that you can undertake just to be sure.

First and foremost, restart the game on Xbox One or PC and then try again. If you’re still encountering issues, other potential fixes would be to reboot your hardware and/or internet router. If none of those simple steps do the trick, you might want to try connecting to a different internet network — just be mindful of any usage costs this might incur.

There is one additional thing to try on PC, though. It’s been reported that first opening Halo Reach with anti-cheat disabled, then quitting and relaunching the standard version of the game with it enabled can temporarily rectify the issue. It’s a process that needs to be repeated each time you come to play the game, so do keep that in mind if it works for you initially and then stops.
