Blockchain - HyperLedger Fabric pt 3: web console

Blockchain - HyperLedger Fabric pt 3: web console

I wrote a series about HyperLedger Fabric blockchain services. 
IBM has provided an open-sourced web console to manage these services. Here I'm reviewing that

image

The console explains how to do the setup for the Fabric network example. There's a script that collects your blockchain's setup and services, and generates metadata for it.
You can import that data in the console, and it sets up all managed objects for you.
The only manual activity is to generate a wallet with Identities that can interact with the chain.

Experience

Install and deploy was easy. The same for importing the metadata.
Once started, you define the Identities that the console will use to manage the ledger.
You define a managing entity for the 2 distributed blockchain nodes that represent two organisations (companies). And one for the ordering service - where the organisations can buy (transfer ownership) from each other.  
You then set these new Identities as the managers of the nodes, and get immediately insight in what's happening.

When I tried to do the same for the ordering service, I get errors.

image

The console doesn't connect to that ordering service. I don't know why. I shouldn't have to set things because the connection info is retrieved from the ledger config.
I've seen related errors on the internet, but none that applies to my setup.
I have done a complete undeploy and deploy a few times but this error is persistent. I used the latest release versions of Fabric and the Console.
I'll update if I get this resolved.

That leaves a mixed experience. The blockchain is working and interaction via CLI is going fine.
The console is interesting and gives a simple view over a fairly complex setup. The Identitiy and Certificate creation wizard is fenominal.
But there's also the error on a standard setup with the standard example. A mixed bag.
