Any idea on what kind of authentication it is asking for? There is already password-less authentication between all the compute nodes and the controller node back and fro.

There should be more information in the compute log file on the compute host slabnode1210.netact.nsn-rdnet.net. In any case, this has nothing to do with ssh, but OpenStack authentication.

My guess: Incorrect config in nova.conf, section keystone_authtoken, on that compute host.

For an example of how this should be configured, see https://docs.openstack.org/nova/queen....

Tried adding configuration details to nova.conf under keystone_authtoken section on that compute host. But still didn't help!

Are you sure your authentication data is correct? Check the compute log for more info.

There is no problem in the authentication data. I double checked it.
