[2020] UNIFORM-01 sign in on Playstation 4 log in issue. Unable to access game.

I've had this issue for a couple of weeks now possibly since the last Division 2 update and done all obvious actions to enhance my internet connection to better improve my connectivity to the internet. I can't understand why I've had no other connection issue in the past playing The Division 2 up until now? My last connection to the game was May 11th 2020 if that is any help to Ubisoft. It's difficult to understand in these circumstances if it's your own connectivity or Ubisoft's servers not allowing players to gain access. Not sure if there's any advice I can take or if so still would not know what to do because I've tried the obvious for my own connectivity. I know others have had this UNIFORM-01 log in issue because I've searched the forums and have found what others have posted about it.
