[pywbem-devel] pywbem.cim_http.ConnectionError: Socket error: check_hostname requires server_ho stname

Hi,

Does anyone know what cause the following code fails and how to make it
work. It seems input param "no_verification=True" in WBEMConnection() is
not working. Here are the infomration:

platform: Windows 7 64 bits.
python version: 3.5.1 (v3.5.1:37a07cee5969, Dec  6 2015, 01:38:48).
pywbem
version: pywbem-0.9.0.dev0
OR
version: pywbem-0.8.2.

python:


=== using 'https' and fails, even no_verification=True is set =========
c:\test\pywbem-0.9.0.dev0>python
>>> import pywbem
>>> conn=pywbem.WBEMConnection('https://usenABCx2l',
... ('admin','#1Password'),'root/xyz',no_verification=True)
>>> ein=conn.EnumerateInstanceNames('CIM_ComputerSystem','root/xyz')
