"We were unable to log you in"

I need help over here. This never happened to me before but when I tried playing overwatch it keeps telling me in the screen that “We were unable to log you in, time out communicating with blizzard services”. I’ve never had this problem before and I restarted my router and battle. net with it not working still. Any ideas on how I can fix this?

What connection troubleshooting steps have you tried?
