requests.exceptions.ConnectionError，这个怎么解决

from operator import itemgetter

import requests

# 执行API调用并存储响应。
url = 'http://hacker-news.firebaseio.com/v0/topstories.json'
r = requests.get(url)
print(f"Status code: {r.status_code}")

# 处理有关每篇文章的信息。
submission_ids = r.json()
submission_dicts = []

for submission_id in submission_ids[:30]:
    # 对于每篇文章，都执行一个API调用。
    url = f"http://hacker_news.firebaseio.com/v0/item/{submission_id}.json"
    r = requests.get(url)
    print(f"id: {submission_id}\tstatus: {r.status_code}")
    response_dict = r.json()

    # 对于每篇文章，都创建一个字典。
    submission_dict = {
        'title': response_dict['title'],
        'hn_link': f"http://news.ycombinator.com/item?id={submission_id}",
        'comments': response_dict['descendants'],
    }
    submission_dicts.append(submission_dict)

submission_dicts = sorted(submission_dicts, key=itemgetter('comments'),
                          reverse=True)

for submission_dict in submission_dicts:
    print(f"\nTitle: {submission_dict['title']}")
    print(f"Discussion link: {submission_dict['hn_link']}")
    print(f"Comments: {submission_dict['comments']}")


以下是报错
