抓取网页时，NodeJs请求错误（ETIMEDOUT）

Question

有时在Node JS中抓取网页时会出现ETIMEDOUT错误（使用localhost作为服务器）。我正在使用Request-Promise发出请求。我找不到处理它的方法，它没有总是给出它，而是随机出现。我试图减少并发性，但是没有用。毕竟，我并不辛苦。有什么建议（使用其他图书馆等...）？

这是错误代码：

用于抓取的代码：

const rp = require('request-promise');
const cheerio = require('cheerio');
const fs = require("fs");
const Promise = require("bluebird");
const moment = require('moment');

async function Gundem () {
    var posts = [];
    try {
        const baseUrl = 'https://www.ntv.com.tr';
        const mainHtml = await rp(baseUrl);
        const $ = cheerio.load(mainHtml);
        const links = $(".swiper-slide.color-white).map((i, el) => {
            return baseUrl + $(el).children("a").first().attr("href");
        }).get();

        posts = await Promise.map(links, async (link) => {
            try {
                const newsHtml = await rp(link);
                const $ = cheerio.load(newsHtml);
                return {
                    title: getTitle ($),
                    newsUrl: $("meta[property='og:url']").attr("content"),
                    imageUrl: $("meta[property='og:image']").attr("content"),
                    time: moment($("time").attr("datetime")).valueOf()
                }
            } catch (e) {
                console.log('error scraping ' + link + '\n', e)
            }
        },
        {concurrency:10}) 
    } catch (e) {
        console.log('error scraping ntv' +'\n', e)
    };
    fs.writeFile('./ntv.json', JSON.stringify(posts, null, 3), (err) => {
        if (err) throw err;
    });
    return posts;
};
