有时无法通过代理访问带有请求的网站http.client.RemoteDisconnected：远端封闭的连接，无响应

问题描述

我一直在尝试使用请求模块通过python中的代理访问网站（在我的示例中，我正在访问api.ipify.org，因为它应该打印代理的ip）。我之前使用相同的程序测试过代理，并且它已经起作用。但是有时候我随机运行它会给我一个错误。这是我的代码：

import requests

proxies = {
 "http": "39.100.18.200:8080","https": "39.100.18.200:8080",}
r = requests.get("http://api.ipify.org/",proxies=proxies)
print(r.text)

它应该打印：39.100.18.200 它以前有，但是随机会给我这个错误：
