python之Python3请求: No connection adapters were found for,错误

import requests 
import xml.etree.ElementTree as ET 
import re 
 
gen_news_list=[] 
r_milligenel = requests.get('http://www.milliyet.com.tr/D/rss/rss/Rss_4.xml') 
root_milligenel = ET.fromstring(r_milligenel.text) 
 
for entry in root_milligenel: 
    for channel in entry: 
        for item in channel: 
            title = re.search(".*title.*",item.tag) 
            if title: 
                gen_news_list.append(item.text) 
            link = re.search(".*link.*",item.tag) 
            if link: 
                gen_news_list.append(item.text) 
                r = requests.get(item.text) 
                print(r.text) 

我有一个名为 gen_news_list 的列表，我正在尝试将标题、摘要、链接等附加到该列表。但是当我尝试请求链接时发生错误:

第一个链接成功。但是第二个出了一个错误。我无法添加内容以列出此错误的原因。我的循环有问题吗？代码有什么问题？
