Master Chief Collection campaign co-op not working? Here’s how to fix it<\/h2>\n

<\/p>\n

\n

Diving into Halo 3<\/em>\u2019s campaign with an online friend (or several) sometimes simply doesn\u2019t…work on PC. You\u2019ll send out the invites and group up, pick and load a mission, and then the game abruptly hangs before kicking you to the main screen. Or you\u2019ll get to play for a short while, and then everything freezes and boots you.<\/p>\n

Either way, you get torn apart and can even lose your progress, both of which are irritating as hell. And this experience isn\u2019t isolated to Halo 3<\/em>\u2014it can happen with other Microsoft games that rely on Xbox Live servers for multiplayer too, be it the rest of the Master Chief Collection<\/em> or Forza<\/em>.<\/p>\n

The problem is usually related to network address translation (NAT) and Windows 10\u2019s Teredo<\/a> service. As a networking issue, it can be a little nebulous to solve, as the reasons for the trouble vary from person to person. To help, we\u2019ve gathered all the major troubleshooting steps you can take (and have had to try ourselves) to fix the problem.<\/p>\n

If you\u2019re having problems with Halo: MCC<\/em>\u2019s online campaign co-op, you\u2019ll very likely see a report similar to this one.<\/p>\n<\/figcaption><\/figure>\n

To summarize the matter, Xbox Live servers handle multiplayer connections for Halo: Master Chief Collection<\/em> (even on PC), and if you\u2019re not connected to them with an open NAT type, it can hinder the quality of your multiplayer experience or outright block co-op play.<\/p>\n

So your ideal end goal in walking through these troubleshooting steps is to achieve open NAT while connected to the servers. Moderate NAT can work as well in select circumstances (see below), so don\u2019t despair if your router won\u2019t cooperate.<\/p>\n
