AWS RDS Node.js连接失败

Question

似乎无法连接到AWS托管的我的数据库。我将出站和入站规则设置为0.0.0.0和公共可访问性。

我能够通过Microsoft SQL Server Management Studio进行连接。但是，当我尝试通过Node.js上的Sequelize连接时，出现以下错误

Unable to connect to the database: { SequelizeAccessDeniedError: Login failed for user 'admin'.

我使用的凭据与通过SQL Management Studio连接时的凭据相同。

Node.js代码：

const Sequelize = require("sequelize");
const sequelize = new Sequelize("database", "admin <same username when I connect through SQL Management Studio> ", "<inserted correct passowrd, not an issue>", {
  host: "<inserted correct host, not an issue>",

  dialect: "mssql",
  operatorsAliases: false,
  pool: {
    max: 5,
    min: 0,
    idle: 10000
  }
});

sequelize
  .authenticate()
  .then(() => {
    console.log("Connection has been established successfully.");
  })
  .catch(err => {
    console.error("Unable to connect to the database:", err);
  });


module.exports.sequelize = sequelize;
module.exports.Sequelize = Sequelize;
