Cant Play on the same network with each other

So Me and my brother play on the same network different xbox’s. We can find a match but when the game loads the bar takes forever but when the loading bar hits 3/4ths of the way it kicks us both every single time. Does anyone know how to fix this issue? Or have had the same bug?

I have also run into the same issue, even during the Halo Infinite. Best thing you can do is file a ticket at Halo Support.

This is a pretty serious issue that I’ve heard people report problems of ever since Halo 5 released. Send in a bug report and if you ever find a solution please say something.
