Unable to open SSL / HTTPS socket with ESP8266: OSError from ssl.wrap_socket

[joseph-long]

I've just set up an ESP8266 with 4MB of flash using esp8266-20210202-v1.14.bin and I'm trying to run some example code to open a socket for https:

import usocket
import ssl

hostname = 'xwcl.science'
s = usocket.socket()
ai = usocket.getaddrinfo(hostname, 443)
addr = ai[0][-1]
print(addr)
s.connect(addr)
s = ssl.wrap_socket(s)

In the REPL, it all goes well until ssl.wrap_socket:

>>> hostname = 'xwcl.science'
>>> s = usocket.socket()
>>> ai = usocket.getaddrinfo(hostname, 443)
>>> addr = ai[0][-1]
>>> print(addr)
('104.238.141.27', 443)
>>> s.connect(addr)
>>> s = ssl.wrap_socket(s)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: -40

Hi. There has been many improvements to ESP8266 and ssl over the last years. Is this still a problem on latest MicroPython version?

There is more information, including tests on recent MicroPython in #400
Proposing to close this issue in favor of that one.
