SSH not working. Can not connect to the VM

I can see back up files in oracle virtual machine but I can not download the back up file to my PC through filezila as ssh connection is not possible. This problem arose after I updated teh ERPNext 7.x to 8.x and following 2 problems might be causing this:

  1. I doubt the Nodejs version is also not right. I don’t even know how to downgrade my Nodejs version from 10.xx to 6.xx

  2. I can also read permission denied.

I have logged in by using
username: frappe
password: frappe.

I can not login with

username: Administrator
password: admin
