installation issue

Hello, I have encountered the issue where I could not update nor download Diablo IV game. I followed many different guides, which led me to uninstall the whole app. Now, the same issue persist, but I can’t even install, as before I am able to press continue in installation process I am receiving the error message: “Whoops! Looks like something broke. We’ll try to fix it, please try again later. More help: BLZBNTAGT000008FC”. Please help.
