You’re we’re disconnected from battlenet. Please reconnect

I was trying to get Diablo installed to my new laptop so I decided to do it at work. I tried to log in and now I’m getting this msg every time I try. I went home and tried to use mobile hotspot and it was doing the same thing. This is highly annoying; I don’t bot, I don’t hack, I don’t do anything like that. Come someone please give me some feedback. If I’ve made an infraction, how long is it going to be?
