Can't log root on Debian VM

[Theodreyz]

Hi all,
on a Debian 8.4, when i try to make a "su -" to connect as root, "acces denied"
What should I do to be able to log in as root ?
i can't connect as root in ssh session, just user
PermitRootLogin yes !
Thanks for your help

Inside a VM, it is however YOU set it up. This has nothing to do with Proxmox.

Since a third station on the same network I try to establish an ssh connection, but the root password is refused when the VM I get to do with "su -".
t is anything to set the proxmox server to make ssh connection to take control of VM?
I can establish ssh connections on Proxmox server but not on the VM

I solved the problem, it was because my keypad was not supported so instead of typing numbers, it hit me symbols.
Now everything is back in order, I finally get to access my VM using ssh
