Log in to the game with VPN on?

Why can’t I log in anymore have the VPN on?

Have used it for more than a year and have not had any problems with it before.

And all other Blizzard games I can have VPN on when I log in to the game but not World Of Warcraft.
Even Blizzard app I have the VPN on when logging in on it.

Using Kaspersky Secure Connection.

I have to get a blue answer on this.

You won’t.

Blizzard don’t support VPN’s. You use them at your own risk, and no support will be offered in their use, or troubleshooting, except from other players.
