I purchased a Slingbox 500 in Mar 2015 and it worked fine until a couple weeks ago when all I can get on all of my devices is a screen that says "This site can't be reached . . . " The site is http://127.0.0.1/vms-ul/index.html. I've tried hard resets/reconfigs multiple times, just downloaded an update and reconfigured, and still get this screen. Any ideas?
