Hi Ragesh,I checked the setup and found that theSSH Algorithms public-key configuration was missing for the devices mentioned and hence the error was coming.I have added the configuration forASR9K-1 and it seems to be working fine now.Please update the configuration forASR9K-2. Refer to the below url to set the missing configuration.Let us know if the issue is resolved and we can close the ticket.Thanks, NikhilThanks Nikhil, Issue fixed on the setup after adding the below ssh config on NSO.set devices global-settings ssh-algorithms public-key [ ssh-ed25519 ecdsa-sha2-nistp256 ecdsa-sha2-nistp384 ecdsa-sha2-nistp521 rsa-sha2-512 rsa-sha2-256 ssh-rsa set devices device ASR9K-2 ssh-algorithms public-key [ ssh-rsa ]TheSSH Algorithms public-key configuration was missing for the devices mentioned and hence the error was coming.The issue was resolved after adding the configuration.
