Firefight issue halo 5

When i run halo 5 and finish a firefight match, the screen says “deploying” during a while, After that, i return to warzone playlist with “contacting dedicated Server” in the top left side of screen. When i try to search a match in any playlist, the Next message appears: An error occurred while searching for players.
I have to run the Game again to play matchmaking.
Andy solutions? ( I play on Xbox)
Sorry for all mistakes, my english isnt so good.

This happens to me frequently too. Sometimes waiting it out fixes the issue and you join a lobby, but most times just restarting the game is the only option. I dont know what causes the issue but I think it related to moving through the menus too quickly.
