Downloading data and disconnecting and reconnectin

I haven’t played halo wars 2 in two days and when I came back to playing it won’t let me play multiplayer, it keeps saying downloading data and on the top left it keeps reconnecting and disconnecting, I’m from the UK and my gamertag is daddyamine please fix this overwatch and TF2 are perfect but it’s this and halo 5 that’s not working which I will post on the halo 5 support thread

I also forgot to mention that I factory reset, hard reset, removed my account (I took the power cable off too) and uninstalled the game
