Reproduces the problem - code sample

try:
        try:
            # import ssl
            # ssl._create_default_https_context = ssl._create_unverified_context
            h.request(req.get_method(), req.selector, req.data, headers,
                      encode_chunked=req.has_header('Transfer-encoding'))
        except OSError as err: # timeout error
            raise URLError(err)
        r = h.getresponse()
    except:
        h.close()
        raise

The third and fourth lines of code were added by myself, but I still reported an error after adding it, and line 8 is where the error was reported
