I don’t know if this is a known issue but since Halo:CE came out on MCC for PC I’ve been dc’ing out of my first game after about 30 seconds in. I’ll get a one minute ban from matchmaking and then I’m good to que into more games with no dc issues, but it happens 100% of the time. Haven’t bothered recreating on Reach although I see no reason to as I’ll only be playing CE/2/3 anyway.
this is happening to me too, seems to be exactly at the 1 min mark.
it happens in reach too except there its not a disconnect, its just a hang. costs a life but not much more
