I decided to replace my older slingbox with an M1. The older one has been working since 2011 on my network at home. I connect the M1 to my network and I see I get an IP address. I can ping it and if I look at my firewall logs I see connections outbound from the IP address. But every time I try to add it to my account using my mobile devices I'm told it can't be found. So I tried using using slingplayer for desktop. But when I launch that all it does is says "Locating slingbox on the network" and then that fails and it says retry. Does anyone have any ideas on what the issue could be?
