Output of openssl -connect

Description of problem:
When accessing https://docs.openshift.org I get SSL connection errors (i.e. using curl: "SSL certificate problem: unable to get local issuer certificate"). 
This makes it impossible to access the documentation from behind a proxy which only allows connections to trusted web sites.

Version-Release number of selected component (if applicable):
Current documentation web site

How reproducible:
openssl s_client -connect docs.openshift.org:443 -showcerts -servername docs.openshift.org

Steps to Reproduce:
1. Using openssl: openssl s_client -connect docs.openshift.org:443 -showcerts -servername docs.openshift.org
2. Using curl: curl -verbose https://docs.openshift.org

Actual results:
1. Openssl:     Verify return code: 21 (unable to verify the first certificate)
2. Curl: (60) SSL certificate problem: unable to get local issuer certificate

Expected results:
No errors should occur. The server should deliver the certificate chain including all intermediate certificates.
