For me Dishanywhere doesn't work on WIFI from any device or PC. It works fine from the cell network or if the PC is connected to the Ethernet. From WIFI I get error 2 code and if I try again I get error 3.
I have 100MB wifi so I know speed isn't an issue. I have a Hopper 3 connected to the network via Ethernet with 3 Joe's.
I tried opening ports 80, 443 & 5678 but it had no effect. I tried putting the Hopper on the DMZ no effect.
It works perfectly if I run it through the cell network, including my Surface Book.
