Error: Incorrect K_g key. Check BMC configuration and try again

Hi!

I need some help from the community. I am with the following issue: one of my servers, after the enlistment step, doesn’t work properly in my MAAS enverioment. My MAAS informs that the Power Configuration of this server is with an error, and shows the following information: Error: Incorrect K_g key. Check BMC configuration and try again

With this error taking place, I am unable to commission the node and, therefore, unable to deploy an OS with MAAS.

After researching a few days (and learning a few things about IPMI), I managed to change the K_g key from the server with the problem and I sucessfully validated the usage of the IPMI through ipmitool, but the problem still continues.

I also made other attemps, like: tried to verify which K_g key my MAAS is trying to use, but I didn’t managed to retrieve this information, and tried to use other types of Power Configuration, but none of them helped me.

Any advices of what can I do and which logs should I be looking for?

This is the setup that I am using:
MAAS version: 2.5.1
Server with Problem: Cisco UCS C22 M3 Rack Server

Regards
