The SSL thing is a very specific problem. But more generally, the base href in the page source was wrong. Check your source code to make sure the base href is correct.
If the base href is correct then it might be the browser not obeying it. Either that or the request for the resource may have just failed for whatever reason. It happens.
The one in the image URL for the browser address bar I would imagine. http://www.gotitans.com/
I hit it several times on the Mac via Chrome, my Windows 8 box using Chrome and never had a problem. I wonder if that user has any specific add-ons enabled.
