When connecting to a Cisco router that is based on IOS-XR, it is unsuccessful with the following:
Receive Connection error Details: Failed to request pseudo-terminal on the remote host LIBSSH2_ERROR_CHANNEL_REQUEST_DENIED
I have tried disabling SFTP and Agent Forwarding.
Here is the debugging info from the Cisco side, I don’t know how to get this from the la terminal side.
