Game will not load. Playing on the PS4. After trying to load a while an error message appears saying I must disable a firewall that I do not have enabled, with a 1023 code. Makes no sense!
Try turning your PS4 completely off (not just rest mode) and then restart and try again.
I have tried to restart my PS4 and also turning it off completely and back on and neither one worked either.
There is something in your internet setup that is not allowing your PS4 to talk to the Four Kings servers. You could verify by taking your PS4 to a friend's house and trying on their internet.
Another idea would be try setting your router to give your PS4 DMZ access, this will open all ports to and from your PS4, that way if still errors you can rule out any blocked ports being the problem due to a firewall setting.
