Exposing local WCF service through Azure Appfabric Relay Service - azure

Question

I've been following the Pluralsight demo from this new course, in the section "Demo: Configure an Existing Service to use the Relay Service".
All is well until I come to the point where I expect to see the services listed in appfabric at https://MyURL.servicebus.windows.net/
Nothing shows up.
I've gone through everything a number of times, checking and rechecking my settings.
My service is hosted in IIS, it's running, the web.config has it set to listen to the above URL, I've configured Auto-start, and it refreshed when I changed the setting, so it should be listening, but yet no services show up.
I had this net.pipe error, and I've followed the fix for that so that no errors show up in the event log.
Anything else I could be missing or that I could check?
How is my hosted service "listening" and how does it "publish" its service data onto the service bus? is there something I can sniff to see how/why it is failing?
I am aware the network setup is important and I need specific ports need to be open etc. Our IT guys assure me the correct ports are open and the machine should be able to get through them.
I have also enabled auto-start on the Site and the service.
Update
I have managed to self-host the service programatically, which publishes the service into the Azure service bus feed and can call the service using the service bus endpoint across the web - this proves the network ports are all open, but I still want to have it hosted in IIS.
Here is my web.config with secure personal details removed (apologies, it's a biggie!)
