I live in Phoenix, AZ. My slingbox solo is in Detroit, MI. I had no trouble with this connection for years, and suddenly am unable to connect. The message that pops up says that there is a network error that makes the connection impossible. I can't figure out what to do, and support would not help because I guess my grace period warranty ran out. Anyone got any suggestions? It would be most appreciative!
What I can see from your post, is that you can't get a connection from a remote location.
In this case, besides discard any streaming restriction from that specific network, what I would recommend is to make sure that the Internet Viewing is properly configured from the Slingbox location.
