Was working just last night. Tried to play today and the game refuses to login. I’ve tried everything I can think of, resetting router, PC, flushed DNS and modem, etc. Everything else is working including Battle.net, which leads me to believe the issue is not on my end.
Posting here to let the devs be aware.
Update: This has appeared to resolve itself on the game’s end after about 40~45 mins
