Pb to connect to the server with FileZilla

to connect with FileZilla to save my database, I do this :
host : files.000webhost.com
my ID and my password found in the file wp-config.php : “DB_USER” and “DB_PASSWORD”
then “connexion”

and I get an error message : “impossible to connect to the server”.

What’s wrong ?

Thanks for your help !
