This also happens to me on varying servers. What I usually do before I launch the game is go where the DayZ is installed, open the BattlEye folder and run the BEService executable. After that, I start the game, join the queue, click leave, then connect to the server again without quitting the game. I've done this the last two times I played and it seemed to connect with no issue.

I agree with this, there really is no point in going inside a dynamic toxic zone, unless you're looking to kill some zombies who might drop a few extra filters.

I should also mention that the Toggle Aiming Down Sights option in the controls menu is completely empty, no key bound to it.
