I can't use Softether VPN to play black desert online

Hi, I was told I can use Softether VPN to play NA Black Desert online with my friends but now when I login the game then turn off the VPN it will automatically log me out??? Am I the only one have this kind of problem?

I’m guessing you’re in a country that can’t play bdo? And that you’re using this vpn to mask your ip as a na one? If so I’m guessing when you turn off your program your ip is no longer masked kicking you from the game

You connect to the VPN, log in on the launcher, hit Play and then instantly disconnect the VPN before XIGNCODE starts loading. The IP check only occurs upon login to the launcher. You can still play on your normal connection.
