Iam using SSHLibrary and particular Open Connection and Login keywords in robot to open a connection and login to a server.
Open Connection host=10.45.11.12 port=31022 timeout=5m
Login username=admin password=Test1234
Iam getting the following auth failure:
KEYWORD SSHLibrary . Open Connection host=10.45.11.12, port=31022, timeout=5m

Note, that the username and password are right.
Also, from the server point of view that we want to login, after investigation we have the following details:
The “linux” device specification is not valid for use with proxy. After the Netmiko SSH client provides the user’s password to proxy, it expects an SSH message indicating that the auth was successful. This isn’t how proxy works. After the password is validated, proxy then enters a keyboard-interactive session where you choose the network element (and possibly credential category, etc.,). Only after you have entered this information and proxy has connected to the network element is the desired SSH auth message sent by proxy to the client, allowing you to open a shell channel and send/receive bytes (in the case of SSH Session) or execute a command (in the case of SSH Command).
