It still doesn't work. When I try to connect to GTS the signal goes green and then red while still on the ``Connecting to Nintendo Wi-Fi'' screen. It eventually fails to connect. No ``Checking GTS server..'', no Pokeball falling from the sky animation. I checked my boxes, the Pokemon isn't in there.
I also assumed that testing connection would work because if I use the Pokemon Fan Event Center (link above) as the DNS, the test succeeds.
