Dear folks,

When I try to ssh a device and down the configuration file am getting an error. Below I'm adding the error am getting.

When I try to access SSH : Orion website is unable to create a SSH session.

When I try to download the configuration file : Unable to connect to polling engine XXX on the relevant server. Verify that NCM 7.7 or later is installed on the server.
