database problem

[eluser]Miguel Diaz[/eluser]
I am trying to connect to my database in my server and it is sending me the error.


A Database Error Occurred

Unable to connect to your database server using the provided settings.


I put all the information but I tried all I know and it is not working I already double check password and username and put a conexion with the same information and it is not working.

Do I have to write something extra when you put and IP instead of localhost this is my connection.

$db['default']['hostname'] = "127.0.0.1";
$db['default']['username'] = "Premio";

I hope someone could help me please.
