Disconnect after FoF Gauntlet 3 game

So after every game I play of the FOF gauntlet 3 in ultimate team, the game will say that it’s unable to connect to server and send me back to the main menu, though I’m able to play every other game mode type in ultimate team and this doesn’t happen, so it’s seems to only be FOF gauntlet that is having this bug, I’ve tried all the troubleshooting solutions that EA have given and even deleted and reinstalled the game but still having the same issue, if anyone is able to help that would be great 

thank is advance
