@Molinko There isnt any error code the server checks if user is online then checks access level if its same or higher then the door access level then it says access granted now thats the part im having a issue with is with the door or server saying access granted as its not sending the data or what becuase the door says access denied
So i have here some programs for a security server door controller and card writer theres a issue where as when you use the card right access level the server says ok but the controller says access denied heres the 3 parts of the code
