Origin won't connect in Sims 4 or in the CAS Demo.

[KathrynBliss]

I was able to download TS4 through Origin and install it. But whenever I play, it constantly tells me I am offline and that I cannot connect. This isn't a Sims 4 issue, it's an Origin issue - or at least it is for the computer I am using, because the same thing is happening in the CAS demo. I tried to access my gallery on my laptop and it wouldn't work. I went and tried to access it on another computer in the same  house and I was able to access it from there. Any suggestions?
