Why do I get URLFetch CA certificate error using SocialMedia with Facebook?

John Griffith, MITRE
Posted 10 years ago

I have authenticated to Facebook and am trying to view my friend network with following command, but I get the errors below. I am behind a firewall, but I can retrieve web pages correctly with URLFetch directly, so it doesn't seem to be a proxy problem.

Thanks for any help, -- John

In[4]:= SocialMediaData[{"Facebook", "FriendNetwork"}]

During evaluation of In[4]:= URLFetch::invhttp: Peer certificate cannot be authenticated with given CA certificates. >>

During evaluation of In[4]:= General::stop: Further output of URLFetch::invhttp will be suppressed during this calculation. >>

Out[4]= SocialMediaData[{"Facebook", "FriendNetwork"}]
