Matchmaking still not working

Matchmaking never works for FFA and war zone assault games. If I wait long enough, I’m prompted with the message, “Unable to find match, insufficient players.” I doubt this is true. Im in Australia by the way. Is anyone else facing these issues?

Open NAT?

good luck with anything other than Warzone and Slayer in Aus mate, most Aussies cant connect to alot of gametypes
