So, I looked for in file config.php (inside include folder) the entry that can be like the error's one and I found this:

// ****** MASTER DATABASE SERVER NAME AND PORT ******
// This is the hostname or IP address and port of the database server.
// If you are unsure of what to put here, leave the default values.
$config['MasterServer']['servername'] = '213.215.228.XXX;
$config['MasterServer']['port'] = 3306;

Really the xxx of the number 213.215.228.XXX hide digits but are not the same as the ones reported in the error.
I have tried to substitute the file in this way and to upload again on the server:

// ****** MASTER DATABASE SERVER NAME AND PORT ******
// This is the hostname or IP address and port of the database server.
// If you are unsure of what to put here, leave the default values.
$config['MasterServer']['servername'] = 'localhost';
$config['MasterServer']['port'] = 3306;

But the problem is that the error stay, even if different...!!
