How do I downgrade to 2.0.2?

Long story short, the server got busted and my hosting provider hasnt replied yet. I want to move my site to new server. I had incremental backup set up. I have the password thing so I installed cyberpanel to the new server but there is no SFTP option there. Heard it was removed because of some bugs. So I tried to downgrade to 2.0.2 but did not work.
I tried to install older version, same problem. I really need SFTP option in incremental backup so that I can restore the site. Please help.
Dedicated Server, Hetzner, Ubunto 20.04 (also tried with CentOS 7)
