Won't let me search a match!!!!

I have halo 3 multiplayer downloaded in mcc. I can load a custom game and it lets me in bit everytime I try searching for a match it backs me out after 2-3 seconds.

I’ve got a friend who is having the exact same problem. Last night I was having the same issue. Uninstalled and then reinstalled halo 3 and it worked…until the morning. Now it’s doing the same thing again. Wtf??? Anyone got a fix?

Btw, my buddy has the whole game installed and the same problem is happening…

This is a common issue.
Apperently it is cause by being idle. Of course the idleness is calculated after 10-20 seconds for those who wrote here on waypoint about it. Personally I have no problem at all: I never click any button when I’m searching and I’ve never been kicked out of the research.
So I’m quite sure it is this ‘idleness’ thing: you are no the first one who writes here about being unable to complete a research suddendly after 2-3 seconds.
I hope and think they ar egoing to fix it with the january update.

Yeah OP, there have been a few other threads about this.

But probably best to post about it in the MCC Multiplayer Feedback - January thread.
