Are you getting a BLZBNTBNA00000A8D error on the Battle.net desktop app?
The error indicates that there’s an issue with your connection to the server.
In most cases, the error is a glitch/bug with the login function and not a connection issue.
Editor’s note: I’ve personally encountered the error once before and I found a way to fix it.
The error message appeared when I logged out of my Battle.net account and tried logging back in.
In this guide, you’ll learn how to fix the BLZBNTBNA00000A8D error on Battle.net when you can’t connect to the server.
How to Fix BLZBNTBNA00000A8D on Battle.net
To fix BLZBNTBNA00000A8D on Battle.net, you need to continue offline, launch a game, and log into it.
You can also try switching your region (e.g. from Asia to Americas) in the login screen by clicking on the gear icon.

Editor’s note: When you get the “BLZBNTBNA00000A8D” error, you’ll have two options—retry or continue offline.
If you select “Retry”, you won’t be able to log in and you’ll get the same error message again.
On the other hand, if you select “Continue Offline”, you’ll be able to access the Battle.net app where you can launch a game.
By launching a game like Overwatch 2 in offline mode, you’ll be promoted to log in using your Battle.net account.
After you’ve logged in, the game will start in online mode and the Battle.net log in issue will also be fixed.
Fix 2: Change your region
- On the Battle.net loading screen, select the gear icon.
- Change your region under “Login Region”.
- Wait for a few seconds.
- Try to log in to your Battle.net account again.
Editor’s note: Changing regions is an easy way to fix Battle.net login issues.
For example, if your region is “Asia”, try switching to “Americas” and wait for a few seconds.
After waiting for a few seconds, the login button and social icons should appear.
Before you launch a game, make sure to switch back to your original region.
