Host is not allowed to connect

This is a mysql problem, so ill post it here, so, the other one dont matter

On all my pages, where i use mysql, i have this now :

Warning: mysql_connect(): Host 'server.goetic.fr' is not allowed to connect to this MySQL server in /home/graphiks/domains/graphiks.net/public_html/crons/nbr.php on line 6
Erreur : Host 'server.goetic.fr' is not allowed to connect to this MySQL server

I dont use server.goetic.fr to connect to mysql, i use server.tonserver.com ...

server.goetic.fr does not exist anymore ...
Im lost there

Thx,
Sky

If someone knows what to change, it would be realy good, because all the website using mysql are down

One thing strange, DA can connect to mysql ... I tried to use the same login host and password as DA, but, no better luck ...
