This page, FAQ from Battleye, is suppose to help. https://www.battleye.com/support/faq/ "When connecting to a BE-enabled server I get kicked with a request to restart my game. This is happening because you permanently declined BE installation by clicking “Do not ask me again.” in the BE Launcher window previously. To fix this please go to the “BattlEye” folder in your game directory (e.g. “C:\Program Files (x86)\Steam\steamapps\common\Destiny 2\battleye”) and double-click the “Install_BattlEye.bat” file to install BE." Doesnt work for me.
