Network matchmaking or server browser didn't work

inside the menu, always have no network or X when click inside it. so i didn’t try anything in the matchmaking or like BL2, server broswer etc. the game just launch in March on stream,and in the achievement, not many got LV50 etc, so there should have many player who is playing the game . but the game network isn’t work well, i check either my region or the world, u find nothing,or the game can’t find it.

it’s on PC, steam, as i just completed the main quest, LV52 , so i am still working on farming and understand the skill system etc , on mayhem 2
