So the first thing to check is that you have the right IP and
password...  open a console on the MAAS server and try to get some
response with amttool (and make sure you actually have amttool
installed):

bladernr at critical-maas:~$ AMT_PASSWORD=<YOUR AMT PASSWORD> amttool 10.0.0.10
### AMT info on machine '10.0.0.10' ###
AMT version:  9.1.0
404 Not Found at /usr/bin/amttool line 242.

amttool doesn't work with AMT 9 or newer, but will at least return a
version string if the login and IP are correct.  So if that fails,
then you need to check the credentials in the node's power settings.

Incorrect.  That entry on the Power settings is for the IP address
that the BMC already owns.  If you have set AMT to get an address via
DHCP in MEBx, then your BMC is set to some other IP address... I never
set BMCs to DHCP for this exact reason. it's too easy for confusion,
and it's also possible that on a renewal down the road, the ME will
get a DIFFERENT IP address for some reason.

In fact, if you look at the MAAS Dashboard, you'll likely see the AMT
ME listed there as a device if you have discovery on.  But as I said
before, save yourself the headache, reconfigure AMT with a static IP
and just use that.
