For over 6 months I have been constantly getting this error code and I restart my internet and PS4 every time and never makes a difference. It's a big problem but what I'm most annoyed about is that you have disabled support tickets on your website and it says to try live chat and then that says live chat is unavailable please find another way. Now I put alot of time and money in to this game and to not be able to play it when I want and then to have no support either shame on you. You make more than enough money to fix these problems?
