My PS4 isn't letting me log in

Minecraft on my PS4 will not let me login in and every time I click sign in a little box appears saying that there is a problem logging in.  I already tried deleting and re downloading the game as well as checked to see if parent controls turned off my cross platform play however deleting the game and reinstalling did not work and my parent controls for cross platform play says it allows it please help as soon as possible. Thank You!
