Windows Putty with authorization keys not WORKING

Hi There,

I have tried all the Tutorial about how to enable a WINDOWS Client connect with SSH after generate keys.

I could add the public key to the DROPLET using :

cat ~/.ssh/id_rsa.pub |
ssh username@203.0.113.0 “mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys”

I could also check that the authorization key from the CLIENT MACHINE i need grant access is there after the step above

BUT … Even with this … Putty receives a “Server Refused our key” error message and ask me for root password.

Please I need this instructions as I CONSTANTLY need to aprove another CLIENT to access DROPLET .

Waiting for return
