Can anyone help how to fix this?
Thnx in advance

Answer 1

Your request might be going through a local proxy.

Answer 2

Upgrading to Python 2.7.9 fixed this for me.

Answer 3

You need to paste your proxy's certification to the end of google_appengine/lib/cacerts/cacerts.txt

Answer 4

This does seem to be related to proxy servers, when I run fiddler and try to deploy I get this error. When I shut it down deployment works fine.
You will get an invalid certificate error like
fancy_urllib.InvalidCertificateException: Host 127.0.0.1:8888 returned an invalid certificate (_ssl.c:507: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed):
So turn of the proxy server (assuming this is your issue) you are running and and the run the appcfg deploy!
