Fix Overwatch Error BN-564: Connection Troubleshooting Guide

You are staring at the login screen and the BN-564 error code is stopping you from getting into your games. This usually means there is a handshake issue between your device and the Blizzard servers, often caused by a simple network hiccup or a corrupted game file.

Why this happens

Error BN-564 is a generic connection failure, most commonly triggered by localized network instability or a temporary outage on the Battle.net service side.

Steps

1. 01
   Check the Blizzard server status on a site like Downdetector to rule out a regional outage before changing your own settings.
2. 02
   Unplug your router from the power outlet for a full 60 seconds to clear its cache, then plug it back in and wait for the lights to stabilize before relaunching the game.
3. 03
   If you are using a Wi-Fi connection, connect your PC or console directly to your router with an Ethernet cable to eliminate packet loss issues.
4. 04
   For PC users, open the Battle.net launcher, click the gear icon next to the Play button, and select Scan and Repair to fix any corrupted game files.
5. 05
   If you are on console, sign in to your account at account.battle.net/connections, remove your linked Xbox or PlayStation account, and then re-link it to refresh your authentication token.

Still not working?

If you are still seeing the error after these steps, check your firewall or router settings to ensure Port Forwarding is configured for Battle.net services. If you are on a university or public network, the local admin may be blocking the ports required for game authentication, in which case you might need to use a VPN to test if a different route resolves the connection.
