Unable to log into Ultimate Team

Hi guys

I'm facing an issue where I'm unable to log into UT but all the other game modes work fine including seasons, I've already tried restoring the licence, creating a new blank squad, uninstalling and reinstalling the game aswell as changing the DNS and settings in my router, I've tried signing in and de linking my account aswell as re linking it back, but still no luck, any suggestions guys as this is a real problem for me.
