I'm getting the same thing! i'm not EVEN trying to go online i'm trying to play alone offline! and i get this! I already have dayz standalone that i play but i wanted to try the arma 2 dayz mod i used to play it many years ago. But now im starting to think the arma 2 dayz mod just doesnt work anymore I see no reason why this shouldnt be working, This is the 2nd day i've been trying to get this to work i'm starting to see why some other commented why they just uninstalled it but i dont want to do that i played it before so if anyone knows please let me know i'll try the site you posted hopefully that will help! Thank you!
