Log in issues desktop

I can log in fine into the desktop account, and even restarted my computer and deleted and redownloaded the desktop app 3 times. Changed my password 3 times and yet still. When I try to launch the battle net application on my computer it still is saying it can’t verify my credentials. I have strong internet connection and no other application running in the background. Still can not log into the desktop application and Its been doing that for the past 24 hours.

Can you clarify what you mean here? The PC Bnet app should be where you login with on desktop, but you also said you can’t login to it:

Did you mean something else in the first part I quoted? The website maybe?
