either that or the server process is bound to the local network address and therefore trying to call the process through its external address isn't going to get a response.

Maybe, if you were to show what the nested exception is.

That is, seemingly, not a publicly available ip address (i.e. can't be reached from the internet, at all), or you are attempting it to access throught the wrong interface on your computer, and so have no network path to it.
