SSLEOFError: EOF occurred in violation of protocol (_ssl.c:1129)

我的环境是基于Anaconda的，我创建了一个环境来开发，这是细节，python 3.9.7.

我已经尝试了 this，但是没有用，我的 tls 是 1.3，下面的也不行，我已经坚持了好几天了。有人可以帮我吗？谢谢！

pip install ndg-httpsclient
pip install pyopenssl
pip install pyasn1

Answer 1

我不知道这是什么 VPN，但看起来它在干扰流量。

这种行为在使用公司 VPN 时很典型，这也意味着在访问 Internet 时使用公司过滤。通常在此处实施深度包检测以控制和限制访问，这可能会导致故意中断传出连接。

我把urllib3版本降到1.25.11，然后就解决了。我读了 here 并且有效。
