Thanks Tony. We're looking into it.
I rebooted both of my routers and when I connect, I can't get in on my phone or my computer, so must be something with my routers but no clue as to why I'm now having issues.
I did some playing around and when I turn off my Wi-Fi, I can get in on my phone.
So now I'm thinking it's our ISP as another CT member on friendly is having the same issue.
