PuTTY Disconnected : no supported authentification methods available (server sent : p

[tomtomtom]

Hello;
I use PuTTy to connect to the OMV ROCK 64.


I just want to connect simply with login and password.
I try to add a SSH public key, but no success.
So i delete PuTTY, clean config and reinstall.
I try to connect simply with login and password.
But when i put the login, this message appears.

'PuTTY Disconnected : no supported authentification methods available (server sent : publickey)'

Putty stop at :

Code:

login as: root

Do you know if i could connect log/pass again or it is a server issue, and the only solution is to fomat / reinstal OMV on the ROCK 64 or may i try to connect directly (with keyboard and screen) the Rock64 ?
