Yep. did that and set it up totally wired. Same error.
I can "cancel" out of the "cannot connect to mydink.com" and view the camera by inputting the IP address into a web browser, but I really wanted to be able to view via my mobile phone over a mobile network. I have tinycam monitor app (android device), and that works, as long as I'm on wifi. When I try to view over 4G, I get a "cannot open a private IP address over a mobile network" error.
