ValueError: check_hostname requires server_hostname. Can you run it through a Visual Studio or another IDE and see how the hostname is resolved?

@vicktw do you use proxy? Could you ping https://api.binance.com? Or open in browser this site https://api.binance.com/api/v3/ping There must be the following page:

Looks like you're being blocked somehow. Use curl or ping to see that you're not blocked by either Binance or your own network/firefall. Or do what Alex, just saw it :D
