Pyro "could not find NameServer"

[Chuckk Hubbard]

The docs say to try to discover the URI on my own if this happens.
Could I get a hand doing that?
This isn't just something I want to solve on my machine, e.g. by
changing my network setup or what not; this is a program I hope to
distribute and I hope my users can avoid having to deal with this,
because I suspect they won't.
Thankye.

Here's what I typed and what I got:
