Ericsson TCU Login Issue - SSH Permission Denied After Successful Method Previously

Hi team,

The above screen is from an Ericsson TCU system. Whenever attempting to log in via SSH, it shows a “Permission denied, please try again” message after entering the password.

I recall that there was a specific step or method we used before that allowed the login to succeed, but I’m unable to remember the exact process now.

Could someone from the Ericsson team please assist with the correct steps or guidance to resolve this?
