Can't find Fireteam games in lobby (Call of Duty Black Ops: Cold War)

tell me, in your lobby you find the games Fireteam (all-around and destruction) this is where the dirty bomb and combined arms combat. I have not found any players in the all-around or in the destruction in general for a long time! From the word, not a single player enters the party at all and does not connect me to anyone. ! Can you check if it's just me or everyone? It can't be that no one played these modes at all!? everything is ok with other modes, quickly finds players
