Hi,

When I implemented "Networks" panel, I usually did debuging with two steps:
(1) Does quantumclient get an expected data from quantum server?
(2) Does Horizon display an expected result?

According to your mail, quantumclient does not receive what you expect.
If so, debugging quantumclient can easily be done by using python
interactive shell as below:

I hope it will help you.
