ErrorCode 3.0

When attempting to connect with either my phone or through the EA PC Client, I am repeatedly getting an "ErrorCode 3.0" error. The game will not load, despite the suggested restart.

On my phone I have deleted the game, restarted my phone, and reinstalled the game. The issue persists, regardless of whether I am connected to wifi or using carrier data.

I have no issue connecting with my tablet on a different account, which is connected to the same wifi network as my phone and PC.

Edit note: This may be an account specific issue. I have no issues logging out and back in on my second account.
