Trying to do D4 update and get error code BLZBNTAGT00001389

[moio-21299]

Tried to install the D4 update. Got to 84% and an error message comes up. “Whoops. Looks like something broke. You could try restarting Battle.Net”. Error code is: BLZBNTAGT00001389
Have tried all the suggestions, including uninstalling Battle.Net and reinstall. Nothing has worked. So basically… help! Thanks for any advice given

Hey there moio,

Thanks for taking the time to report this error! This specific error code is typically caused by a conflicting third-party program (such as antivirus), damaged/corrupted local Battle.net files, or a problem connecting to the patching server. Please try the following steps to help narrow it down:

1. Fully update or temporarily uninstall antivirus programs which may be interfering with your connection to the patching server. If you’d like more information on troubleshooting security applications, click here

2. Reinstall the Battle.net Desktop App with these steps:

   • Uninstall the Blizzard Battle.net App (skip Step 6 for now, we will re-install later).

   • Next (before re-installing) let’s delete any Battle.net, Blizzard, and/or Blizzard Entertainment folders in the Windows temporary file locations below. If you don’t see all 3 folders in each location, that is okay—just delete the folders you have):

   • Press Windows Key + R and type: %LOCALAPPDATA%. Delete any Battle.net, Blizzard, and/or Blizzard Entertainment folders.
   • Repeat the process for %APPDATA%, %TEMP%, and %PROGRAMDATA%. Delete any Battle.net, Blizzard, and/or Blizzard Entertainment folders.

   • Finally, re-install the App.

If the problem continues, temporarily test a different network such as a mobile hotspot to determine whether the problem is isolated to your current network.

Hopefully, one of these steps will do the trick. Please let us know if you have any questions or run into additional issues.

For anyone else having this issue. I used two command functions in my Command Prompt. First make sure you run it as admin and us these two functions. 1.sfc /scannow 2.dism /online /cleanup-image /restorehealth. Hope this works.
