Unable to add host via DHCP

Support
1

Hello, I am unable to add a host on my new Katello system. I receive the following error:

Create DHCP Settings for myserver1.example.com task failed with the following error: ERF12-6899 [ProxyAPI::ProxyException]: Unable to set DHCP entry ([RestClient::BadRequest]: 400 Bad Request) for proxy http://dhcp01.example.com:8443/dhcp

I am running Katello 3.7 and the Foreman proxy on a Windows DHCP server. I can retrieve an IP address just fine. However, when I finalize a new host I receive that error up above. On the Foreman proxy, I get the following error:

Any idea what this could be from, or how I can resolve this? Thanks.

Hello,

your smart proxy version is no longer compatible with Foreman you are running. This change added new flag related_macs and it seems to break MS DHCP provider: Feature #17533: Using a bonded interface as provision interface should provision DHCP for all child macs as well - Foreman

Upgrade your smart-proxy to the last stable version or the version that katello 3.7 ships with.

That worked. Thank you.
