Could not log in to Battle.net

Hello,
I’m having an issue since yesterday whenever I try to login to the battle.net desktop app I get the message “Could not log in to Battle.net”

I have tried all blizzard suggested fixes including reinstalling the app, changing the password, clearing the cache but nothing seems to work.
I am able to connect to battle.net in browser but the app won’t work.

Please tell me how to fix this.
Thank you!

same for me battle net starts select game and then nothing was playing yesterday but bow cannot play black ops or modern warfare. tried scan and fix and nothing

I tried a 2nd time to redo everything and apparently resetting the router did the trick…
