Connecting to Ultimate Team is not possible at the moment

Every time I  play a game in UT whether it's Squad Battles, Rivals or any of the others, it allows me to play the full game and then on completion it tells me that connecting to Ultimate Team is not possible at the moment and kicks me out of the game. When I log back In I have the DNF Modifier message.

Is there a solution to this because this has caused me to lose points in Squad Battles and drop down rankings in Rivals. 

Every other feature in game is working normally.
