You have to specify the key that you want to use to log in I think. Open putty, go to Connection > SSH and click on Auth. There select the Private key file.
Then you go to the top and either save the settings or you enter the IP and click Open

Not sure if thats even the issue though but seems like it because the server wants a key instead of password
