Jim,

When you're sending requests to `api.system-domain`, you're talking to the
Cloud Controller. I'd suggest you start by taking a look at the Cloud
Controller logs. You can grab them with `bosh logs` or by SSH'ing to the
VM and cd'ing to /var/vcap/sys/log. Hopefully that'll show you an error or
stack trace.

How to I do diagnosis to find out the root cause?

Thanks all.
