axios 配置 proxy 请求失败

我想用 axios 通过远程代理去做一个请求，但是一直返回错误。
我换用 HttpsAgent 就可以，请问这是为啥？

import axios from "axios";

axios.get('https://www.google.com', {
    proxy: {
        protocol: 'https',
        host: 'xxx.yyy.com',
        port: '443',
        auth: {
            username: '123456',
            password: '123456'
        }
    },
}).then(r => {
    console.log(r.data)
}).catch(e => {
    console.error(JSON.stringify(e))
})
