I have Foreman 1.9.0 installed with foreman-chef 0.1.7 and chef 12 Enterprise on a separate server. I am using MS DHCP and MS DNS proxies on a separate windows server. When attempting to delete a node, I get an error: ERF12-4348 [ForemanChef::ProxyException]: Unable to communicate with Chef proxy, ERF12-0944 [ForemanChef::ProxyException]: Unable to communicate with Chef proxy, 500 Internal Server Error

Deploying a host on VMware also adds the foreman node so the proxy connection seems to work just fine.

The DNS entry gets deleted. The DHCP reservation does not get removed. The Chef Node does not get removed. The Host does not get removed.
