Server login failing

Hello All,

I am new to this platform an trying to complete my first task under Nautilus Deployment Architecture where I have to create a non-interactive shell for a user. I am trying to login to the app02 server though ssh using the below information from the github repo.

Whenever I am trying to ssh the server it is denying. Can anyone help me knowing whether the passwords have been changed or is there something else I am missing? Thank you in advance.

ssh [email protected]
then type Yes to accept fingerprint.
then enter password.
If your task is not relate to other server then you are not eligible to access those servers.
