Error code BLZBNTAGT00000840
If you are experiencing an error code BLZBNTAGT000008440 while updating your World of Warcraft installation, you may need to troubleshoot the problem. The most likely cause is a maintenance scheduled for your region. This issue can also be caused by an overprotective Antivirus (AV) suite. To fix this problem, temporarily disable real-time protection or uninstall your AV suite. Another cause may be an addon manager that interferes with the update.
You can try restarting your PC or trying to install the game again. If this still does not solve the problem, you can perform a fresh installation of the game. Make sure you have DirectX 9 installed on your computer. If you cannot fix this issue by reinstalling the entire game, check your storage. If your hard drive is running low, delete applications to free up space. If all else fails, use the steps listed above to repair the issue.
The error may also be caused by faulty network services or slow Internet connection. Check that you have updated all relevant system updates. If they are updated successfully, you should be able to play the game again. If not, you can also contact Blizzard Support or follow @BlizzardCS on Twitter. If none of these steps work, you can run a command-prompt as an administrator to check the status of the game.
Addon manager blocking update
The new UI for World of Warcraft is expected to be more customizable in the upcoming Dragonflight expansion. In the meantime, if you want to use third-party addons, you can disable this restriction by switching to the addon manager. However, this update is a long way off, so there’s no need to panic. In this article, we’ll discuss how you can fix this problem.
If you’re running an overprotective Antivirus suite, it’s possible that it’s interfering with the update. If you notice this issue, try disabling real-time protection for the game for a few hours and then re-enable it. The problem may also be caused by an addon manager. If you’re unable to enable the update because of your addon manager, you may need to disable the service and reboot your computer.
Alternatively, you can manually update the addon. While this may take time, you’ll probably end up with an outdated version of the addon if you don’t manage them in an efficient way. Deadly Boss Mods, for example, regularly updates. In the meantime, you can use CurseForge, a popular repository for World of Warcraft addons. Once you have installed the right addon manager, you can now update it.
Third-party antivirus blocking data transfer between client and server
If your firewall is blocking data transfer between the client and server, your antivirus may be to blame. Fortunately, there are a few ways to fix this issue, and reinstalling the antivirus may fix the problem. First, try connecting to the network via LAN cable, instead of Wi-Fi. If the problem persists, reboot your computer in Safe Mode. Alternatively, you can update the firmware of your router.
