Remote login error

When I try to use remote login on my iPad outside of my network I get this error message:

DVR Access Failure
A server with the specified hostname could not be found

I am in the channels beta app -> settings -> Login to Remote DVR -> connects to the getchannels login page -> hit the authorize button -> opens the channels beta app and that is the message from the app.

Please make sure the Remote Access option at the bottom of the DVR setting UI is enabled, and that my.channelsdvr.net works
