Kicked out of UT when submitting an SBC

Anyone else having this issue? 

Suddenly started about 30 minutes ago, I can open UT, Sign in, build the SBC but when I submit... I get kicked from UT.

Wondering if its an EA server issue or I have been soft banned? (Unlikely if others are experiencing this).

I mean, I'm only doing the SBC that they have on the game, and not even buying players to complete it!

Not sure why there would be an issue!!
