Problem need help!

Everytime i try searching for a game and spartan ops it finds some players then when it is setting up the game the search restarts, I have tryed about 10 times now and it keeps happening even 1 time there was only me and 1 other guy in the spartan op lobby and i felt bad because i think he has to play the mission alone now,

I started playing this game again a few days ago and it has never happend before with any other games i play online.
