May be you are using key based authentication and probably while re-installing, you may have lost the private keys. Tell your server admin to provide you the new ssh keys.

Log in as a regular user instead. For one thing, root should be disabled unless you have two servers automatically replicating, or something similar. Secondly, root logins are disabled in Ubuntu. I don't use Ubuntu, so maybe disabling PAM (UsePAM no in /etc/ssh/sshd_conf) and using rsa or dsa keys for authentication would bypass this issue. For logging in manually, it is best to log into a regular account and use sudo. The root account is one that hackers will bang against in a brute force attack.
