Sorry I posted before listing the problem by accident. I'm seeing an message (seems like the message in "inside" the player software) that says "This webpage is not available" The webpage at http://rvashow.appspot.com/Viewer.html? chromium.
We didn't make changes to DNS, not using OpenDNS, etc. Under "Display", our display is showing as "Offline", so I'm not sure what/why this is happening since I haven't made any changes that I can think of that would affect this.
