Reproducing client request issues in Python

[Tridays]

English:
I am using Python to reproduce a client request and want to connect to a node through socks to send the request. However, I encountered an issue where requesting HTTP is normal, but requesting HTTPS does return the following message. I kindly ask for your guidance

我使用python复现客户端请求，想通过socks连接节点发送请求，但是我遇到了一个问题，请求HTTP是正常的，但是请求HTTPS确返回如下信息，还请各位大佬指点
