Smart Proxy Infoblox DNS records not being created

The DNS module does load, according to the logs. I tried setting in dns.yaml from enabled: https, to enabled:true, restarted foreman-proxy, refreshed smart proxy on foreman front end, create host now gives the following error:

Unable to save
Create IPv4 DNS record for dev-testvm79 task failed with the following error: ERF12-2357 [ProxyAPI::ProxyException]: Unable to set DNS entry ([RestClient::RequestTimeout]: Request Timeout) for proxy http://foreman-proxy:8443/dns

Checked log, says 200 now, so not sure what the problem is now:

D, [2018-01-31T22:34:46.991060 ] DEBUG -- : close: 10.x.x.19:57960
I, [2018-01-31T22:35:00.941659 ]  INFO -- : 10.x.x.19 - - [31/Jan/2018:22:35:00 +0000] "POST /dns/ HTTP/1.1" 200 - 75.2232

I will troubleshoot more tomorrow, exhausted right now.

Thanks for your help.
