webスクレイピングしようとするとurllib.error.URLError:と出る。

以下のコードを実行するとエラーが出ます。
原因がわかりません。

該当のソースコード

import urllib.request
from bs4 import BeautifulSoup


class Scraper:
    def __init__(self, site):
        self.site = site

    def scrape(self):
        response = urllib.request.urlopen(self.site)
        html = response.read()
        soup = BeautifulSoup(html, 'html.parser')
        with open("output.txt", "w") as f:
            for tag in soup.find_all('a'):
                url = tag.get('href')
                if url and 'html' in url:
                    print("\n" + url)
                    f.write(url + "\n")

Scraper('https://news.google.com/').scrape()

上記のコードを実行すると以下のエラーが発生します。（長いです）

試したこと

最後の方のurllib.error.URLError: 以降のエラーコードをググってみたところSSL認証？が降りない　ような事が言われていて、以下のコードを加えて実行したところ、確かにエラーコードは出ないのですがシェルになんの反応もありませんでした。
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
