This may be a firewall issue. It was for me.

I was experiencing the same symptoms much of you described and tried most, if not all the remedies mentioned in this thread.

Check to make sure there are UDP and TCP inbound rules set up for the Battle.net Launcher.exe in whatever firewall service you use. For me it was just the off-the-shelf Windows defender which you can access in the start menu by typing firewall and it should pop up. Regardless what sort of firewall you use, there should be a relatively easy way too ‘COPY’ a rule.

Simply copy the UPD inbound rule for Call of Duty Modern Warfare.exe and paste it as a new rule. Name it whatever you like but be sure the Program (executable) points to the Battle.net Launcher.exe file (for most in Windows it’s under the ‘C:\Program Files (x86)\Battle.net’ folder.

Rinse and repeat for the inbound TCP rule.

I believe what happened is when I first installed Battle.net I was using a third-party antivirus that handled the firewall rules. I uninstalled that antivirus and some time after is when I was experiencing the issues above. I suppose the Battle.net installation process ‘sees’ my default firewall provider and adds the necessary inbound rules to only that location.

Let me know if this works for anyone (I hope it does so you can meet my Swiss). I’ll try to check this every so often in the next few days and happy to help more if needed.

EDIT : I don’t think it would be the other way around (adding the Warzone executable) because that’s installed AFTER the battle.net app and I’m assuming you folks didn’t go to bed, or bake a casserole while installing a new antivirus/firewall program for your rig before you started the Warzone download.

Disabling Windows UAC (User Account Control Settings) is what fixed it for me.

This has nothing to do with UAC. This addition is laughable.

Grazie dell’aiuto , ma non sono un tecnico non me ne intendo molto
