"https://{ILO_HOST}/redfish/v1/chassis/1/Thermal" not returning any meaningful data

[MCowher-HT]

I'm having trouble getting the application to work. I'm investigating the URL from the Subject line (with the host name populated of course), and this is being returned:

{"Messages":[{"MessageID":"Base.0.10.NoValidSession"}],"Type":"ExtendedError.1.0.0","error":{"@Message.ExtendedInfo":[{"MessageID":"Base.0.10.NoValidSession"}],"code":"iLO.0.10.ExtendedInfo","message":"See @Message.ExtendedInfo for more information."}}

I'm on the patched version of ILO 2.77 that allows fan control.

Oddly enough, if I hit this URL: https://{ILO_HOST}/json/health_temperature, I get plenty of meaningful data back, including the "currentreading" value that ilo-fans-proxy.py is looking for:

I also get this result from "https://{ILO_HOST}/json/health_fans":

{"hostpwr_state":"ON", "fans":[ {"label":"Fan 1","location":"System","status":"OP_STATUS_OK","speed":13,"speed_unit":"Percentage"}, {"label":"Fan 2","location":"System","status":"OP_STATUS_OK","speed":13,"speed_unit":"Percentage"}, {"label":"Fan 3","location":"System","status":"OP_STATUS_OK","speed":13,"speed_unit":"Percentage"}, {"label":"Fan 4","location":"System","status":"OP_STATUS_OK","speed":13,"speed_unit":"Percentage"}, {"label":"Fan 5","location":"System","status":"OP_STATUS_OK","speed":15,"speed_unit":"Percentage"}, {"label":"Fan 6","location":"System","status":"OP_STATUS_OK","speed":19,"speed_unit":"Percentage"} ]}

turned out it was an SSH communication issue. Had to add the diffie-hellman-group1-sha1 key exchange.
