Update fails with BLZBNTAGT00000BB8 error

Due to a failing hard drive, I recently had to reinstall my iMac and copy data back to the replacement drive. This seems to have broken WoW, resulting in a BLZBNTAGT00000BB8 “Whoops! Looks like something broke. Give it another shot” error that (or so I gather from trying to find how to fix it) is essentially a catch-all that means “we have no clue what went wrong”.

The exact situation is that I was running macOS 10.14.6 Mojave before and now 12.0.1 Monterey. First, I simply copied both the Battle.net launcher and the whole WoW folder straight from the old drive to the new and ran the launcher and tried to start WoW TBC Classic. When this didn’t work, I reinstalled the launcher. Still no working game, so I had it un- and reinstall TBC Classic, which it did. It then said the game needed an update, but when I click the button, within a few seconds it gives the error mentioned above.

I’ve read things about quitting and restarting the launcher, killing the Agent process, reinstalling the game, and more, but nothing I tried actually worked. A friend also recommended moving the entire WoW install out of the Apps folder, which I tried too (I put them into a folder in my home folder instead), but it gave the same result. I then uninstalled both retail and Classic, thinking to reinstall them to ensure they’re working from their new location. However, installing either fails with the same BLZBNTAGT00000BB8 error, so I now have no WoW installed at all.

I suspect the problem lies in the Agent app. When the Battle.net launcher starts, the OS tells me that Agent wants to make changes, so please enter my password to allow it to do that. Until I do, in the Battle.net launcher the button to start the game has the text “Updating” on it and the progress bar (at 0%) below it; after I enter my password, the text changes to “Update” with no progress bar, and when I click that it begins to update and errors out as described above.

A hard drive breaking sucks!
However this error has a whole list of troubleshooting steps to try which you can find here, however I’d say to start with deleting the battlenet files as this will delete Agent and force the Battlenet app to re-download it which will hopefully fix it :slight_smile:

Thanks, but the method described there doesn’t work either :frowning: I deleted the Agent as described there, which didn’t help, then the whole Battle.net folder, and that also had no effect. The same error keeps popping up at the same times as before.

What I also just tried, is running the game from my old, failing-but-not-dead-yet, hard drive (hooked up as an external one). This produces exactly the same problem now but it didn’t last week when I tried the same with the computer booted from a temporary disk running macOS 10.14.6.

Could there be an issue between Agent and macOS Monterey that is causing this?

Edit (a few days later because the forum won’t let me post a reply before someone else does) Okay, the solution turned out to be to eradicate (almost) everything Blizzard-related from my computer. That is to say, I moved all of this to the trash:

  • The Battle.net app and the whole WoW folder in /Applications (after moving my addons and screenshots out of it).
  • Both the Battle.net and Blizzard folders in /users/Shared.
  • Most of the contents of the Battle.net and Blizzard folders in ~/Library (I only left the stuff related to other games in there).

After doing that, I re-downloaded the Battle.net app from the Blizzard site, installed it, and then had it install TBC Classic. That worked, and once it was done, it ran like it should.

The only thing here is that I lost all the preferences for my addons but, oddly, not WoW’s own. I suppose the latter are stored on the server while the addon prefs are stored somewhere deep in one of the WoW-related folders I deleted.
