Cannot connect to MySQL database from OVH server – Phpmyadmin

I cannot connect to my database which is hosted on OVH remotely from Flutter’s package mysql1 and get the following error:

flutter: SocketException: Failed host lookup: ‘saintlouqpweb.mysql.db’
(OS Error: nodename nor servname provided, or not known, errno = 8)

I usually access it through phpMyAdmin where I have three fields to fill: the server, the user, and the password. I use exactly the same values than there with mysql1 on Flutter in addition to the database name (the server field of phpMyAdmin being the host field of mysql1).

I have searched for hours a solution but I still find nothing on this forum and on the web. Everything is always brought back to a ‘localhost’ server or a problem too different from mine.

Here is the piece of code causing the error :

Future<List<dynamic>> getData() async
  {
    try {
      final conn = await MySqlConnection.connect(ConnectionSettings(
        host: 'saintlouqpweb.mysql.db', // the exact server name entered on phpMyAdmin
        user: 'myusername',
        password: '*********',
        db: 'mydatabasename',
      ));

    var results = await conn.query(
      'SELECT * FROM `mytable` WHERE ID=1;'
    );

    return results.toList();
    } catch (e) {
      print('$e');
    }
  }

I would be grateful if someone can help me about that or experienced the same issue previously.
