Миграция с windows на ubuntu

разрабатываю приложения словаря для себя. приложение прекрасно работает на windows 10. суть приложения клиент - reactjs (с ним проблем нет), работает в windows 10 и в Ubuntu 22.04.3 LTS. с server - проблемы. сервер на express с подключение к базе данных MySQl через sequelize. база данных создана, служба MySql активна , пароль для рута и для базы данных одинаковый. но при запуске сервера на Ubuntu у меня ошибка. в целом всё приложение работает в windows 10 без ошибок и так как я того хочу. `

пример кода подключения к дб:

const sequelize: Sequelize = new Sequelize('dictionary', 'root', '11111', {
        dialect: "mysql",
        host: 'localhost',
        port: 3306,
    });

собственно сам сервер

const start = async () => {
    try {
        await sequelize.authenticate();
        await sequelize.sync();
        app.listen(port, () => {
            console.log(`Server running at http://localhost:${port}`);
        });
    } catch (e) {
        console.log(e);
    }
};

start();

Собственно сам вопрос ,что мне делать и куда бежать? как исправить ошибку подключения к базе данных? P.s. извините , что дал много ненужной информации.
