So even well after the MTU bug fix I STILL cannot get into Halo 5 multiplayer or Co-Op this is seriously bugging me, I've tried starting a thread on reddit, tweeting @Halo and received no response.
All I get is a message.
Unable to connect to Halo 5 guardians lobby service.
I've tried hard resetting, fresh install. Everything. Nothing has worked.
Has anyone ANYONE been able to get a solid fix for this yet??
My NAT is Open, my MTU is above 1300, my upstream is 105mb and downstream is over 26mb.
I'm at a loss for what the hell is wrong
Up and down are reversed, FYI
I would imagine it's your router.
