Comment 3 for bug 1993916

It doesn't give any details on what's wrong, but most likely the password isn't considered strong enough, since we have seen hints toward that before.

Could you please manually try to set different passwords and see if that's the case, and maybe also check what the rules for your system are?

To work around it, you can set the username and password manually in both the BMC and MAAS, and then check "Skip configuring supported BMC controllers with a MAAS generated username and password" when commissioning the machine.

The traceback you see should be harmless. It means that your machine is advertising that there is a Redfish host interface, but it's probably disabled.
