ValueError: check_hostname requires server_hostname

[ZhangGang12]

Describe the bug I can't connect client, but I use the v2rayN proxy client on my PC. When I try to visit https://api.binance.com/api/v3/ping through my browser, It shows ‘{}’. But I try to run the following code, It prints "not existed". So what should I do?

import socket
try:
    socket.gethostbyname('https://api.binance.com/api/v3/ping')
except socket.gaierror as ex:
    print("not existe")

To Reproduce

client = Client(key , serct)

    self.ping()

I'm not an expert on python but I found a work around. you need to install PySocks

Then add the following code to your python script, assuming your proxy is localhost and port is 8888

import socket
import socks

socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, '127.0.0.1', 8888)
socket.socket = socks.socksocket

Moreover, you will need to disable system proxy in v2rayN

Thank you very much! According to your method, the problem is resolved !!
