Overwatch is a team-based multiplayer first-person shooter developed and published by Blizzard Entertainment. Overwatch can be considered as a new genre of game. In fact, Blizzard describes it as a “hero shooter”. Recently, PS 4 players have been facing the Overwatch error bn 564 problem, so we are here to help you guys out.

Before that, let’s talk a little bit more about Overwatch for new users. In a typical match, the game assigns players into two teams of six. Each player gets to select from a roster of over 30 characters, known as “heroes”. Each hero has a unique playstyle that is divided into three general roles that fit their purpose. Players on a team work together to secure and defend control points on a map or escort a payload across the map in a limited amount of time. That’s the premise of Overwatch.
Let’s see how we can fix the Overwatch error bn 564 problem. This error only affects the PlayStation 4 and isn’t applicable for Xbox One or PC users.
If the BN-564 error code pops up on your screen when you start Overwatch, the first thing you should do is check if the game is in maintenance. You can check the Blizzard CS Twitter to confirm this. If it’s in maintenance, you’ll have to wait for a while and try again. This means that the problem is not on your end.
If the game isn’t in maintenance and the servers are running smoothly, the issue could have to do with your account connection. You can solve this by unlinking your Blizzard account from your PlayStation. To do this, select Account Settings on Battle.net, click Security & Privacy, choose Connected Accounts, and click Disconnect.
Once you’ve disconnected, close and restart Overwatch on your PlayStation and the BN-564 error code should vanish.
If you would like to relink your Blizzard account to your PlayStation, there are another few easy steps. It’s essentially the same but in reverse order.
Log in to your Connections on the Management page and click the Connect button next to the PlayStation icon. You’ll then be redirected to the PlayStation website, where you should be able to select the Link Accounts tab in Options. Once you’re there, click Link Account, login with your Blizzard account, accept the permissions to the Blizzard app and finally click Continue. This should fix the problem.
