Does Redfish Power type require SSL for managment?

Setting up Redfish power management for some systems. Because documentation isn’t full as of yet for Redfish, I’m doing trail/error on most of the nodes.

Nodes show up, displays “powered on”, but cannot power of/on via MaaS.
I can curl a redfish session and initiate a restart via CURL with a -k switch to ignore insecure sites. MaaS will display when system is On or Off, but cannot initiate the restarting.

Curious if there’s some Cert requirements.
