Server Disconnects at start of games (ALL of MCC)

Games Halo: The Master Chief Collection
1

Whenever I play online with my brother from the same LAN, Its very common that one of us will get disconnected at the beginning of a match.
Its always one or the other though.
Never both of us.

This happens probably 1 every 5 games

When 2 of my brothers queue up with me the disconnects are almost 1 every 2 games

Is this a known issue?. We never disconnect in solo queue situations

I saw this brought up ages ago in the forums but it didn’t really get any attention and i didn’t see anyone from 343 acknowledge this issue

Hoping theres an easy fix for this, because its getting really old waiting for my brothers game to finish so we can queue up and search again, or waiting our bans to expire from all the disconnecting -.-

I have 6ms ping to Aussie servers and have 0 issues with MCC apart from this.

Anyone else having this problem?

This is more than likely a NAT issue, either in terms of the router running a very strict policy, or the software not being able to cope with the NAT level filtering itself. Unfortunately I can’t help diagnose this as I’m the only one who plays at home. Interesting issue though. If it is the software, then there’s not much you can do, but if you can, perhaps open up your NAT security slightly and see if it works (even if temporarily).

Bear in mind, if you’re using ISP-given routers, chances are they won’t give you access to NAT restriction policies, or UPnP.
