Conquest is not working for me

I was hoping someone could assist me Im new to BF4 and Conquest does not work for me every other game mode works (Im not sure if i need to do something to unlock it) when i open up the game it says make sure your on you PS+ Account which i am but it says Unable to connect when i try to get on a server for conquest.

Same deal. All I could play was small tdm and rush lobbies

I can play the different game modes, but the game freezes after one match. Really fucking annoying

If im lucky I can get into Conquest. Otherwise im in the same boat with you. I gave it multiple tries. Everything else I can play but not Conquest.
