Is Battle.Net Down? Live status & outage reports

Service info and troubleshooting

Launcher won't launch or crashes on start

If the desktop client refuses to open or dies immediately, start with the basics: delete the Battle.net cache folder (found in %ProgramData%\Battle.net\), then relaunch. If that doesn't help, run the client as administrator and check whether your antivirus is quietly blocking the process — Avast and Windows Defender are known offenders here.

Login errors and authentication failures

Error codes like BLZBNTBNA00000005 or 'login failed' usually point to one of these:

• Credentials entered incorrectly — try resetting your password via the Blizzard account page
• Two-factor auth app out of sync — resync the authenticator or remove and re-add it
• Account locked after multiple failed attempts — wait 30 minutes or contact support
• Regional server issues — check the Blizzard support status page for your region

Game download stuck or painfully slow

If a game install freezes at some percentage or the download speed is a fraction of what your connection can do, open the app settings and switch the download region to the nearest server manually. Also limit background bandwidth usage — the client sometimes throttles itself when another Blizzard process is running.

High ping and lag in games

High latency inside a match while your internet feels fine elsewhere usually means a routing problem between you and the game server. Run a traceroute to the Blizzard server IP for your region and look for where packet loss starts. Switching from Wi-Fi to a wired connection alone can drop ping by 20–40ms in many home setups.

Payment not going through

If a purchase fails at checkout, first confirm the billing address in your Blizzard account matches exactly what your bank has on file. Try a different browser or clear cookies — stored session data sometimes breaks the checkout flow. If the card keeps getting declined, your bank may be flagging the transaction; a quick call to them usually resolves it within minutes.

Game files corrupted or missing

When a game crashes with asset errors or refuses to start, use the 'Scan and Repair' option in the client next to the Play button. It checks file integrity and re-downloads only what's broken, so you don't have to reinstall the whole game.
