D2 - Last night fine, this morning "not responding"

I was playing Diablo 2 last night when my VPN started up of its own accord. When I realized why I lost connection, I turned it off, and was able to keep playing. This morning though, I went to log in, and I’m getting the “Battle.net is not responding. Please try connecting again in a few minutes.” message. I just wanted to see if I had landed a ban because of this, and if so, what I can do? Thanks!

Edit: I originally put the wrong error message.
