Foreman » Smart Proxy

When I add host in foreman I get following error in GUI:

Create IPv4 DNS record for cary-lannigan.example.com task failed with the following error: ERF12-2357 [ProxyAPI::ProxyException]: Unable to set DNS entry ([RestClient::BadRequest]: 400 Bad Request) for proxy https://foreman-01.example.com:8443/dns

in logs I can see:
