Admin Login Issue 2.4.4

Hello i’m getting an issue after moving my live 2.4.4 website (example.com) into a staging subdomain (testing.example.com)
As you can see in screen shot i have broken CSS in admin login and also not working
but i’m sure that username/password are correct

Also frontend works fine i have this issue only for backend

  1. I already cleared cache /var/cache and /var/page_cache by FTP and also from composer with
    chmod -R 777 generated/ var/ pub/ (frontend) and
    rm -rf var/cache/* and var/page_cache/* (backend)

  2. I also run some CSS fixing but nothing
    sudo php bin/magento s:s:d –area adminhtml -f
    and sudo php bin/magento s:s:d en_AU -f

Any other suggestion or check that i can do?
Thanks
