Disconnection

I used to play this game quite often however I stopped playing regularly in March. So I hop on Halo last week and I remember all of the fun I used to have, things were great… Until I kept getting disconnected about 40%-60% of the way through a game. I’m in the EU, is anybody else having this problem I did not have this happen to me before I took my break. I also lost a Legendary xp boost the other day which is the main reason I am making this thread.
