Halo 5 Warzone Match Problems?

A couple days ago, while playing in Warzone, the game just take me out from a match (mainly on Mythic Warzone) just from nowhere like if I just quit the game on the last round. It was just on Attack on A.R.C., then, starts again on March on Stormbreak and then on Warzone against other players. My brother have the same issue and told me that at the beggining of the match half of players “quit” from both teams.
Someone have seen this before? I doubt that my internet have failures or lack of mps. And it’s kinda frustraiting 'cause I’m trying to get the SR152 and don’t want a banhammer.
Any solution?
