I can’t connect to a matchmaking lobby. NAT is open, wired fiber connection. What’s going on?
I can connect, but with a 2man team I cant connect to swat, somethings fishy.
I cant connect
Progress? Is a fix in the queue? When can we expect this problem resolved?

So mine says, Fireteam cannot find a suitable Server and this is my fix…Let me say before you proceed that, your halo error might say something completely different such as server sync whatever. Mine has always said Fireteam cannot find a suitable server.Ive had the problem since the first doubles playlist.Ive managed to make it work by…
step 1
turning off xbox,
step 2
hard disconnecting the Ethernet from back of box
step 3
Connecting back ethernet
step 4
turning xbox on
step 5
signing in to your account on dashboard.(I have auto signed in turned off, did this because me and my girl share boxes, im sure this makes no difference but if you feel it makes a difference, try it.)
step 6
boot halo 5-done-I done this multiple times now to know it works… I did have it not work maybe once or twice, all I did was repeat, and try again.Ive done it enough to where I can possibly make a video, if I get enough requests ill make one,(although I dont think its necessary.)Its a HUGE issue, I hope 343i acknowledges the issue. 
Hope my fix helps you guys, if it works for you, share share share
