Hi everyone, I have just started playing Halo 5 online this week, and I´ve been experienced an issue very often. As the tittle says, I get the “Lost connection to the server” message when finishing a game, I still receive EXP and REQ points, the problem is that I also get the banhammer and it wont let me play for almost an hour! I did my research through the forums and found similar problems since last year, The problem is still a thing or just an issue from my side? I´ve checked my connection, no lag and it happens only with this game.
Try going wired if you aren’t , this game plays poorly on Wi-Fi.
Hold the power button down on your Xbox until it shuts off completely it fixed it for me
