Hello

Are you attempting to access SSH via a password or a SSH key? If with a key, check that the key is authorized via:

"WHM Home » Security Center » Manage root’s SSH Keys"

Thank you.

key authorized ...

What command are you using for SSH access? Are you using a specific SSH client, and are you attempting to make the connection from your desktop or another server?

Thank you.

Two diffrenet Cpanel server , I want log to server 2 from server 1 .
it can do over WHM but in SSH command line not !

ssh [email protected]

You will need to ensure that you call the SSH key directly. EX:

ssh -i /path/to/id_rsa [email protected]

Also, make sure the authorized private key is imported to the server you are making the SSH connection from.

Thank you.

Private key files should have 0600 permissions, whereas public key files can have 0644 permissions. Please ensure you have authorized the public key file on the destination server that you are attempting to access via SSH.

Thank you.
