Can't play a single game

So. I am in USA right now , but whenever I try to play a game on the battle net, I am met with korean users playing from korea with a red ping making it impossible to play a game on the battle net. How do I fix this issue?? I try changing my region to U.S connecting to U.S server but all i see are koreans in korean server

Hey SlowNSteady,

Are talking about Ranked games or Custom games?
