Вопрос MySQL, Как убрать ошибку

[AyyLean]

Вот ошибка: MySQLNonTransientConnectionException: Data source rejected establishment of connection, message from server: "Too many connections".
Я не понимаю почему она выдается, потому что я где то все время вызываю эти методы? или не
С mySQL работаю в первый раз.

Спойлер: Метод где выдается ошибка

public void addPlayer(Player player) throws SQLException {
        Connection connection = getConnection();
        Statement statement = (Statement) connection.createStatement();
       
        statement.executeUpdate(String.format("INSERT INTO player_info (name, level, xp) VALUES ('%s', '%d', '%d')", player.getName(), PlayerLevels.getLevel(player), PlayerLevels.getExp(player)));  
       
        connection.close();
        statement.close();
    }
