Are you trying to load into the PS4 NA megaserver?
If so, the reason you cannot login is because there is currently an issue on this server leading to login issues for players.
Thank you. I kind of felt silly when you so easily explained this as I couldnt find info on it here in tye forums. I must have missed it a dozen times, thanks again. May as well remove this post if you didnt already. Sorry haha.
