python 请求收到错误 61 连接被拒绝，但 postman 使用相同的 GET 请求

Question

在我发布这个之前，我花了 2 小时搜索了一个解决方案，但没有一个成功，所以最后我在这里

我尝试使用requests和urllib.request并放入user-agent header 但仍然得到ConnectionRefusedError: [Errno 61] Connection refused denied
然而它在 postman

the url I am trying to get the html page content is https://fangj.github.io/friends/season/0101.html

为什么这段代码不起作用？

import sys
import json
import requests
from bs4 import BeautifulSoup
from fake_useragent import UserAgent

ua = UserAgent()

headers = {
    'user-agent' : ua.chrome
}

url = 'https://fangj.github.io/friends/season/0101.html'

res = requests.get(url, headers=headers)

print(res.content)

错误如下
