如何解决Python请求代理错误无法连接？

我尝试在 Python 中使用代理进行 ip 轮换，但每次都出现此错误。我用谷歌搜索了这个问题，但找不到答案。

我使用此站点的代理：https://free-proxy-list.net/

HTTPSConnectionPool(host=''github.com'',port=443): Max retries exceeded with url: / (Caused by ProxyError(''Cannot connect to proxy.'',Remotedisconnected(''Remote end closed connection without response'')))
HTTPSConnectionPool(host=''github.com'',port=443): Max retries exceeded with url: / (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x000001E464274D90>,''Connection to 160.238.227.153 timed out. (connect timeout=1.5)''))
HTTPSConnectionPool(host=''github.com'',NewConnectionError(''<urllib3.connection.HTTPSConnection object at 0x000001E4647D8850>: Failed to establish a new connection: [Errno 11001] getaddrinfo Failed'')))
HTTPSConnectionPool(host=''github.com'',port=443): Max retries exceeded with url: / (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x000001E464274D30>,''Connection to 47.242.225.248 timed out. (connect timeout=1.5)''))
check_hostname requires server_hostname

这是我的代码。

from requests import get
from requests import Session
from lxml.html import fromstring
import random
import time

def get_session(proxies):
    session = Session()
    proxy = random.choice(proxies)
    session.proxies = {"http" : proxy,"https" : proxy}
    return session

def get_proxies():
    proxies = []
    url = "https://free-proxy-list.net/"
    response = get(url)
    doc = fromstring(response.content)
    
    for tbl in doc.xpath("//*[@id=''proxylisttable'']"):
        ips = tbl.xpath("//tr/td[1]//text()")
        ports = tbl.xpath("//tr/td[2]//text()")
        https = tbl.xpath("//tr/td[7]//text()")
        
        for i in range(len(ips)):
            ip = ips[i]
            port = ports[i]
            is_https = https[i]
            if "." in ip:
                proxy = None
                if is_https == "yes":
                    proxy = f"https://{ip}:{port}"
                elif is_https == "no":
                    proxy = f"http://{ip}:{port}"
                proxies.append(proxy)
    return proxies

def main():    
    for i in range(5):
        s = get_session(get_proxies())
        try:
            print("IP: ",s.get("https://github.com/",timeout=1.5).text.strip())
        except Exception as e:
            print(e)
        time.sleep(3)
            
main()
