I'm not ble to add DEM and ADM to my ESMI. Previously we had an ESM to which these two devices (DEM and ADM) were mapped but the ESM had some issues so we did an RMA of the devices, Now I'm not able to add DEM and ADM to the new device as I'm getting the error as attached with screenshot. I'm able to do telnet to both DEM and ADM and even do SSH from my ESM console, But when I'm trying to add these devices I'm getting the error. All the devices are of same version 9.1.3. Please guys help me out here.
Please run the following command from the CLI of the ADM and DEM to reset the keys to default and rekey the devices again.
cat /etc/NitroGuard/factory-id_rsa.pub > /root/.ssh/authorized_keys2
all the best, ;-)
