Halo MCC Insider don't find matches

Disclaimer English is my second lenguaje so if there is some grammar or lexical error just omit.
Hi, I downloaded mcc insider last week, joined on play time at 7 PM pdt, had it searching matches for 15 minutes and it found nothing. At first I was disappointed at the game, thought nobody was playing it, but then some youtubers started posting videos and captures on twitter and I realiced It was just me who couldn’t play. Tried 4 more times during playtimes, and nothing, I don’t know why the game doesn’t pair me with players.
Any help is well received.
