PythonRequest在尝试请求网站数据时接收指针错误

Question

我目前正在使用Python 3.7.6，在Jupyter笔记本中运行代码，并尝试使用库“request”检索网站数据，但收到一个指针错误-

代码：

from bs4 import BeautifulSoup
import requests

source = requests.get('http://bvmf.bmfbovespa.com.br/indices/ResumoCarteiraTeorica.aspx?Indice=IBOV&idioma=pt-br').text

错误：

OSError: [WinError 10014] - The system detected an invalid pointer address in attempting to use a pointer argument in a call

[...]

NewConnectionError: <urllib3.connection.HTTPConnection object at 0x00000179055507C8>: Failed to establish a new connection: [WinError 10014] The system detected an invalid pointer address in attempting to use a pointer argument in a call

注意：当我尝试在我的个人电脑上运行完全相同的代码时，它可以工作，但是当我尝试在我的工作上运行时，它不能工作

这实际上是一个代理问题。 在以下代码更改后，我可以访问网站的内容-

proxies = {
    "http": "http://myproxy:myport"
}

source = requests.get('http://bvmf.bmfbovespa.com.br/indices/ResumoCarteiraTeorica.aspx?Indice=IBOV&idioma=pt-br', proxies=proxies).text
soup = BeautifulSoup(source, 'html.parser')
