The reported address 127.0.0.1 is not a problem.
Phex determines it's correct address from every new connection its making. So even if you switch IPs Phex will recognize and update it address.
127.0.0.1 is only reported since Phex didnt know any better and you have'nt connected yet.
Phex will not report loopback or any other local network addresses to other peers.

Your initial connection problem might be related to a outdated host file. In this case Phex will need some time to determine fresh addresses and connect. You can help by pressing the GWebCache button.
When you run Phex regularly every couple of days you will connect very fast. Phex will prioritize peers by its connection probability and improve its host cache while its running.
