PHPMyAdmin access denied for user

Question

I'm trying to make a minecraft plugin. I'm using ouiheberg to host my server and they give 5 databases with the server. So, I tried to put something in the database but it always returns me << Access denied for user 'mylogin'@'%' to database 'Points' >>.

I have checked in the USER_PRIVILAGE table and I've USAGE privilege. I don't really know if I have all permissions or not but I think no because I can't insert in the table so.

I didn't specify that I'm using PHPMyAdmin and MySQL server 2.

My code :

public static void savePoint(String name, double x, double y, double z) {
    String url = "jdbc:mysql://45.140.165.82:3306/Points";
    String login = "mylogin";
    String mdp = "mypassword";

    Connection connection = null;
    Statement statement = null;



    try {
        Class.forName("com.mysql.jdbc.Driver");
        connection = DriverManager.getConnection(url, login, mdp);
        statement = connection.createStatement();

        String sql = "INSERT INTO Points (name, x, y, z) VALUES ('" + name + "', '" + x + "', '" + y + "', '" + z + "')";
        statement.executeUpdate(sql);
    } catch (SQLException | ClassNotFoundException e) {
        e.printStackTrace();
    } finally {
        try {
            if (connection != null) {
                connection.close();
            }
            if (statement != null) {
                statement.close();
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
