If you play Overwatch 2, you may encounter the BN-564 error, which randomly interrupts your connection to the game. Sometimes, this error occurs during Blizzard server maintenance periods. The BN-564 error can happen on both consoles and PCs.

Main ways to fix the BN-564 error in Overwatch 2

The BN-564 error may be server-side or due to issues with the user’s device. Here are several options and methods that can help you tackle this technical problem.

 

1. Check Overwatch 2 server status

Since Overwatch 2 operates in real time, game servers may often go offline for scheduled or unscheduled maintenance. You won’t be able to join the server temporarily due to server maintenance. To confirm if it's a server issue, check server status using Downdetector. This service tracks game outages and issues. Check Blizzard’s social media for updates. Sometimes, developers announce scheduled maintenance on official channels and note when servers may be down. If the server was under maintenance, you’ll just have to wait for it to restart.

2. Log out and log back into your Battle.Net account

The second method to fix the BN-564 error is to re-link your gaming platform account (Steam, Xbox, or PlayStation) with Battle.Net. This has helped some users avoid the error after server updates.

  • Log into your Blizzard account on the Battle.Net website
  • Hover over your name in the top left corner of the screen and go to account settings
  • Go to the “Connections” tab and disconnect your selected platform account
  • After disconnecting, reconnect your account

This method often helps to resolve network errors and restore access to the game.

3. Restart the device on which the game is installed

If the error persists after checking the first two causes, try a full device reboot – this can help clear temporary network cache issues. Restart instructions for the game (Best method):

  • Close Overwatch 2 on the device and restart the game, ensuring it is completely closed.
  • Turn off power to the PC or console for 2-5 minutes before reconnecting. You may also turn off the router for 5 minutes.


Restarting any device is a simple way to clear the temporary system cache and resolve network errors, helping you restore and stabilize your Battle.Net account.
