"Left Fireteam" Issue

Over the past few days I have been experiencing connection
issues with halo 5’s warzone modes, mainly Warzone Firefight. For example,
I would go into a match of Firefight and everything would run smoothly, but

then all of a sudden, I would just get dropped from the server and it would
say “left fireteam” and I would end up back at the main menu. I got dropped 4
times today and it honestly sucks because I love halo and seeing this stuff happen
just makes my heart break. this problem also includes server crashes, sudden freezes,
and being just generally disconnected from the server. If you come across this problem,
let me know in the space below and if you have a solution, that would be awesome. Thank
you for your support!

My friends has the same issue and it sucks that I can’t play with him because it keeps making him leave the fire team we’re trying to find a solution but can’t this kinda sucks

No known fix for this has materialized, but I recommend you go wired with an open NAT. This will resolve most disconnects.
