Since finally getting Origin to work again (remember the problems I had with it wanting me to update to Win7) I have not put Origin in offline mode. In fact as stated it wanted to download earlier today an update for Dragon Age: Origins. So the problem doesn't appear to lie with a connection issue at all as Origin itself is in online mode and can download updates. What I might do is force it into offline mode and then reboot it back into online mode and see what happens.
Edit: No joy on the switching back and forth between offline and online modes.
Though I do seem to have a separate problem with Origin though. When I close Sims 4 out, the Play button remains greyed out and I am unable to launch Sims 4 again, I have to close out Origin and then restart it before it will let me launch Sims 4 again.
BTW I am going to have to wait to try and fix the connection problem, assuming there isn't a fix before then, tomorrow. I have to be at work shortly.
