OpenSSL python ssl functions not working?

Question

Python

The code:

import ssl,socket

print(ssl.OPENSSL_VERSION)

s = socket.socket(2,1)
s.connect(("g.co", 443))

ctx = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)
ctx.set_ciphers("ECDHE-RSA-AES256-GCM-SHA384")
ctx.verify_mode = ssl.CERT_REQUIRED
ctx.check_hostname = True
ctx.load_default_certs()
ctx.set_npn_protocols(['h2-14'])

c = ctx.wrap_socket(s, server_hostname="g.co",do_handshake_on_connect=False)
c.do_handshake()

print(c.selected_npn_protocol())

I get an error from calling set_npn_protocols():
NotImplementedError: The NPN extension requires OpenSSL 1.0.1 or later.

At the very beginning of the program, there is an output of the openssl version:
OpenSSL 1.1.1g 21 Apr 2020

So why doesn't it work

Answer 1

pip install --upgrade pyopenssl
