Hello admins:

Do you use Fail2ban? If yes then it's possible that it bans your IP. Try to connect it over a VPN or from another VPS.

You had changed Your VPS's ports too.
Just changed back to 22 and its working again.
For accessing your VPS for testing the login stuff, I have reseted the root password & vnc password to default(as mentioned in your VPS Request) and also rebooted it.
