Hey there,

This message is a result of an expired authentication cookie stored on the system. You should be able to resolve this by simply deleting the file in question and relogging in. This should happen automatically upon login but if its been a very long time, sometimes that really old cookie can’t be replaced by the game.

1. Open file explorer/file manager (Right Click Windows Start)
2. Type the following into the address bar (not the search bar): %LOCALAPPDATA% and press enter.
3. Navigate to Blizzard Entertainment\ClientSdk
4. Delete Cookie.bin
5. Empty the recycle bin.
6. Relaunch the Desktop Application and Gameclient to connect and re-authenticate.

That should solve the issue for you and let you play normally. /salute!
