2] Open Battle.Net as an admin

But this is a bit tiring as every time you need to open the app, you have to follow this two-step procedure. That’s why we brought to you a way by which you can always open Battle.Net with the required privileges. Follow the given steps to do the same.
- Right-click on Battle.Net shortcut.
- Select Properties.
- Go to the Compatibility tab, tick Run this program as an administrator.

Finally, restart the computer and check if the issue persists.

- Right-click on World of Warcraft and select Scan and Repair.
- Click Begin Scan.
Wait for the process to complete, restart your computer, and check if the issue persists.
4] Disable VPN or Proxy
If you are connected to a VPN or a Proxy server then you should immediately disable it as your computer is not able to connect to the WOW server. This happens because your system can’t fathom which server it needs to get connected to. Hence, you should disable such services and try again.
5] Disable the Firewall or whitelist the app
If you have a third-party antivirus or if you have configured Windows Firewall then maybe, they are blocking your game from getting updated. So, if you have third-party antivirus, you can disable it and then try to update your game. In case, you are using Windows Firewall, try allowing the game through it and see if that works. Keep in mind that, if you are disabling the security, you are putting your computer at risk of getting hit by viruses and malware.
Antivirus is not the only service that can interfere with your program. There are some other apps that can do the same. So, troubleshoot in Clean Boot to know the culprit. Then, you can remove it and resolve the issue.
6] Reinstall Battle.Net and WoW
If nothing works, then your last resort is to reinstall some programs. You should start by reinstalling Battle.Net, most of the time, it will resolve the issue. But if it doesn’t then you need to reinstall World of Warcraft. So, go ahead and uninstall the program, then reinstall it and see if that works.
Hopefully, you are able to resolve the issue with the given solutions.
