Stuck on "Battle.net Login" screen with rotating icon

Desktop App Tech Support

Stuck on “Battle.net Login” screen with rotating icon. No errors, no progress.

Things I have tried:

Uninstalling/Reinstalling the app as an administrator
Flushing DNS via command prompt
ipconfig /release /renew via command prompt
Deleting 100% of appdata, program data, temp data in safe mode and outside of safe mode
Resetting my modem (hard-wired, no router used)
Turning Malwarebytes on and off
Checking hosts file for issues
Reinstalling my basic ethernet drivers on my pc
Opting into and swapping to the beta version of the app
Forwarding the ports that the battle.net app supposedly uses.
Throwing my PC onto the DMZ using my modem.

Things I can still do through the app:

Continue without logging in by clicking the little settings icon above where you put your email address in and choosing that option.
Launch and log in to certain games via the taskbar icon after selecting continue without logging in
^^this leads to a totally blank window - what would typically be the launcher - and another blank window on top of it that says “Battle.net Updates”
Resume updates and then watch games update via the taskbar, also initialized through the taskbar app

Log in to the app using my laptop on the exact same network.

Log in to my phone app
Access my authenticator
Log in on this website
Use literally every other gaming app (Steam, EA, Epic, GOG)

Sounds like something is blocking the connection. Try a VPN or mobile network through the PC. If that works, time to consult the ISP.

Thanks for the quick response!

I don’t have any WiFi capabilities on my PC, but your suggestion did give me the idea of logging onto the app using my laptop on the same network in case it was some sort of hidden wall my ISP was creating.

The app works totally fine on the laptop, whether or not it’s hardwired straight to my modem or connected via WiFi.

I also tried forwarding the ports typically used for battle.net according to google, as well as enabling DMZ on my main PC, but neither of those worked.

Let me know if you have any other ideas - I’d love to be able to play the games that don’t have secondary login screens on the app!

Maybe some software on the main PC that is causing a conflict. Anything anticheat or security-related could be the cause.

I’ve tried a few more things, like reinstalling .net framework, disabling all security on the PC and trying to boot up the app in safe mode with networking - still getting the same issue unfortunately.

Any more ideas would be super appreciated - thank you for your help so far!
