not sure about that because the server is our vendor's.
anyway, I've manage to connect to the server now by including the private key path in the session option.

thanks.

What is "AIX LAM Authentication"? Is your server using some multi-factor authentication?

Hi,
I got this error while connecting to the session:

Connection has been unexpectedly closed. Server sent command exit status 0.
Authentication log (see session log for details):
Using username "xxxxxx".

Authentication failed.

Saw few of the same issues as mine and you only asked for log.
Attached is mine.

thanks.
