Battle.net not working on Ubuntu 17.04

Hey, I’d like to install battle.net on my Virtualbox running Ubuntu 17.04.

I’ve followed the guide posted in: https://lutris.net/games/battlenet/

It does not matter if I try using the 32 or the 64 bit version. Installation works fine so far and I’m closing the login window when it opens. After installation and opening the app it does not show the “Log In” button on the bottom of the window. There is a circle running the whole time and I get a error message of the Blizzard.helper APP. I can’t log in.

Any way to fix that?

Hello.
