I'm trying to use slacker on python 2.6.9 and getting the issue below, on 2.7.10 everything works. Upgrading to newer version of python is not possible in my case. Is there any workaround?
I'm getting the following error :
/usr/lib64/python2.6/site-packages/requests/packages/urllib3/util/ssl_.py:320: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#snimissingwarning.
