I had the same problem. I went to settings, data output, then checked under udp output, the Lat/Long/speed box and the one below it. Then I went back to the network tab, then ipad page, then it said it was outputting to my ip address for the ipad. 49002 in that box. Then into Foreflight, more, and devices and it said I was connected to X-plane. Voila, it worked. Hope this helps.
