Recently, I upgraded my GAE SDK to ver. 1.7.4 and it started to throw ‘InvalidCertificateException’ when I try to run development server. I searched about this error and some people said it goes away with time, but mine didn’t. What should I look into to fix this problem? I am using python framework Django for my app if that has to matter somehow.

$ dev_appserver.py ./

    Quick workaround that I found: delete the file google_appengine/lib/cacerts/cacerts.txt from your installed SDK.

    Starting from the GoogleAppEngineLauncher:

    GoogleAppEngineLauncher/Contents/Resources/GoogleAppEngineDefault.bundle/Content‌​s/Resources/google_appengine/lib/cacerts/cacerts.txt

    EDIT #

    as of google app engine SDK 1.8.1 this file as been renamed to
    urlfetch_cacerts.txt. Still in the same directory and removing it
    still fixes the problem.
