MariaDB Node.js连接器远程连接超时，mysql连接器可正常连接

我有一台运行MariaDB的远程服务器，使用mysql npm包能正常连接，但用mariadb npm包会触发连接超时。
之前在办公环境里，这段mariadb连接代码能正常运行；在家中时，mysql包依然可以正常连接，只有mariadb包连不上，推测不是防火墙问题。

测试代码 #

import dotenv from "dotenv";
dotenv.config();

// ------------------
// mysql driver WORKS
// ------------------

import mysql from "mysql";

const mysqlConn = mysql.createConnection({
  host: process.env.DB_HOST,
  user: process.env.DB_USER,
  password: process.env.DB_PASSWORD,
  database: process.env.DB_NAME,
});

mysqlConn.connect();

mysqlConn.query("SELECT 'OK' AS status", (error, results) => {
  if (error) throw error;
  console.log("mysql status:", results[0].status); // prints "mysql status: OK"
});

mysqlConn.end();

// ---------------------------
// mariadb driver DOESN'T work
// ---------------------------

import mariadb from "mariadb";

const mariaPool = mariadb.createPool({
  host: process.env.DB_HOST,
  user: process.env.DB_USER,
  password: process.env.DB_PASSWORD,
  database: process.env.DB_NAME,
});

async function testMariaConnection() {
  let conn = null;
  try {
    conn = await mariaPool.getConnection();
    const rows = await conn.query("SELECT 1 + 1 AS solution"); // connection timeout error
    console.log("The solution is:", rows[0].solution);
  } finally {
    if (conn !== null) conn.release();
  }
}

testMariaConnection();
