The BB8 error is a generic error. Simply means the Blizzard Desktop Application tried to perform a task and was unable to complete it. Typically because something interfered with the network or on the system itself.

Try doing an extended power cycle on your system. Turn off all devices including the modem. Wait 30 minutes, turn on the modem, wait 5 minutes, turn on any network devices, wait 2 minutes, turn on your computer and try the game.

You can try switching your DNS settings to use a free public DNS servers instead of your ISPs Servers:

We do not have individual steps for specific modems or routers so if you need assistance accessing or updating the devices, contact the device maker/provider.

Sometimes firewall or routing software/hardware will have some advanced settings to prioritize and manage types of network traffic. Normally that is not an issue but we have seen situations where it can interfere with the delivery of the data for our games/voice chat.

Let’s try turning off these features:

QoS
SIP ALG
RoG (ASUS Routers Only)
Security firewalls (Some ISP provided modems)

Not all devices will have these options and the steps for turning these functions off will be different depending on the make/model/software version of the devices and programs involved. If necessary look at the documentation for your security and routing products to find out how to turn these options off.

In some cases there is a corrupt or misconfigured setting within the router or modem. We cannot say what that might be offhand but the easiest way to resolve these conflicts would be to factory reset the router and/or modem.

You may need to look up your specific model for the steps on how to do this and in some rare cases you may need to have this done by the ISP. Feel free to reach out to them for assistance if necessary.

Let’s manually clear the Battlenet Desktop Application and all supporting data from the system. This will not remove existing game clients.

1. Open file explorer/file manager (Right Click Windows Start)
2. Navigate to the folder where the desktop application would normally be installed. Delete that folder if it exists (usually program files x86)
3. Type the following into the address bar (not the search bar): %APPDATA% and press enter.
4. Delete the Bnet and blizzard folders inside the appdata folder if they exist.
5. Repeat steps 3 and 4 with %PROGRAMDATA% %LOCALAPPDATA% and %TEMP%
6. Empty the recycle bin.
7. Now reinstall the app to the C: Drive.

Once the account is created, shut down the computer, wait 60 seconds, restart, log into the new profile and try the app/client.

While I typically save this step as a sort of last resort due to the size of the game client, it does often solve issues like this where other steps sometimes fail.

1. Click Options (gear symbol next to the install/update/play button)
2. Click Show in Explorer. (leave this window open while you perform step three.)
3. Go back to Options and select Uninstall and go through the process to remove the core files and association to the desktop application. (Skip to step for if unable to perform this uninstall)
4. Check the opened file explorer window to see if the game folder was deleted when the game was uninstalled. If it was not, delete the folder manually.
5. Go back to the Blizzard App and reinstall the game client through the Blizzard App.
