My program uses https and runs fine on Linux, but on Windows it crashes:
W10dev:/cygdrive/p: python fextasy.py -D
DEBUG(fextasy.py): verbose=0

The sourcecode here is:
def tcp_connect(host,port):
global sock
message(f"D:TCPCONNECT to {host}:{port}")
try:
sock = socket.create_connection((host,port))
except socket.error as e:
message("E:cannot connect to %s:%d - %s" % (host,port,e.strerror))
return False
sock.settimeout(timeout)
if port == 443:
context = ssl.create_default_context()
sock = context.wrap_socket(sock,server_hostname=host)
return True
Google chrome and firefox both say the certifacte is valid:

Why does Python complain (only on Windows!)?
