Comment 2 for bug 1916860

Hi Chuan Li, thank you for trying MAAS 2.9 and reporting the bug.

As you can see in the release notes - https://maas.io/docs/2.9/release-notes#heading--bmc-param-additions - MAAS 2.9 included several changes around IPMI encryption. In your screenshot you show that Cipher ID 3 is being used, and the error message states that you should check BMC configuration.

What Ciphers does the Lenovo x3650 M5 support? Have you tried different ciphers? Is encryption important to the customer? What happens if you select 'freeipmi-tools default'?
