Invalid and/or missing SSL certificate for URL when calling apiclient.discovery.build

Question

So I'm running my google endpoint locally with dev_appserver.py. I use the API explorer to test the application.

The code I'm using to create the Service, so I can call the API is the following:

from apiclient.discovery import build 
from oauth2client.client import GoogleCredentials
credentials = GoogleCredentials.get_application_default()
service = build('speech', 'v1beta1', credentials=credentials)

I receive an SSL error (Invalid and/or missing SSL certificate), even though when I access the stated URL via browser it works fine (that is, the green padlock shows up).

I'm not sure what changed, but this was working fine not long ago.

I tried to disable SSL checking, but was unable to.

Full logs below:

HTTPException: Invalid and/or missing SSL certificate for URL: https://www.googleapis.com/discovery/v1/apis/speech/v1beta1/rest?userIp=0.2.0.3

Any ideas what could be causing this problem?

Do I have to "install" or update the SSL certificates used by python?

According to App Engine issue 13477 it seems that some of the certificates found in urlfetch_cacerts.txt that is included in the App Engine Python SDK / gcloud-sdk expired 2017-01-01.

A temporary workaround until a new version of the app-engine-python component of gcloud-sdk is released with updated cacerts is to remove the expired certificates with serial=023A76 and serial=023A83 in urlfetch_cacerts.txt located in <your-cloud-sdk-path>/platform/google_appengine/lib/cacerts/
