I'm not able to reproduce the issue. Please re-open this issue if you are still 
having issue with more recent version of Python and OpenSSL.

[issue35324] ssl: FileNotFoundError when do handshake

[Windson Yang]

Windson Yang  added the comment:

>From the docs

Changed in version 3.7: Hostname or IP address is matched by OpenSSL during 
handshake. The function match_hostname() is no longer used. In case OpenSSL 
refuses a hostname or IP address, the handshake is aborted early and a TLS 
alert message is send to the peer.

I guess OpenSSL refuse your IP address and port.

[issue35324] ssl: FileNotFoundError when do handshake

[joseph...@yahoo.com]

New submission from joseph...@yahoo.com :

After upgrade my python from 3.6 to 3.7, one of my program got following error 
msgs and I suppose it is related to the 'ssl' module:

Traceback (most recent call last):
  File "M:\SUPPOR~1\ONEDAY~1\ODD2\lib\site-packages\urllib3\connectionpool.py", 
line 600, in urlopen
chunked=chunked)
  File "M:\SUPPOR~1\ONEDAY~1\ODD2\lib\site-packages\urllib3\connectionpool.py", 
line 343, in _make_request
self._validate_conn(conn)
  File "M:\SUPPOR~1\ONEDAY~1\ODD2\lib\site-packages\urllib3\connectionpool.py", 
line 839, in _validate_conn
conn.connect()
  File "M:\SUPPOR~1\ONEDAY~1\ODD2\lib\site-packages\urllib3\connection.py", 
line 344, in connect
ssl_context=context)
  File "M:\SUPPOR~1\ONEDAY~1\ODD2\lib\site-packages\urllib3\util\ssl_.py", line 
357, in ssl_wrap_socket
return context.wrap_socket(sock)
  File "f:\Anaconda3\Lib\ssl.py", line 412, in wrap_socket
session=session
  File "f:\Anaconda3\Lib\ssl.py", line 853, in _create
self.do_handshake()
  File "f:\Anaconda3\Lib\ssl.py", line 1117, in do_handshake
self._sslobj.do_handshake()
FileNotFoundError: [Errno 2] No such file or directory

The background is, the program works all fine under python 3.6.

I actually use the 'requests' lib which use the 'urllib3' inside. I don't know 
how to fix this so I just report here. I hope some one can help.
