Microgateway not starting on apim-ui

[elkorep]

When starting the app from the AMP in designer, the gateway never starts.

The gateway logs show:

[Wed Oct 4 13:20:45 2017] com.ibm.diagnostics.healthcenter.loader INFO: Node Application Metrics 3.1.0.201710011954 (Agent Core 3.2.2)

But the gateway never ends up starting and doesn't return an error.

This is using the latest from master and using a basic notes template loopback app 2.x
