These sites have been working for years. No changes other then upgrades. This just happened out of the blue.
Note this is also happening on another Media Temple grid server that is not connected to mine.
And just to be sure I purchased a new domain and added it to my current grid service as a subdomain. Installed a fresh copy of CMSMS and experience the same issue out of the box.

Another note: http://jmkservices.us/ is running 1.6.6 "Bonde" and has no issues. on the same grid server as this site:

Some how root domains are being rewritten to look like HTTPS and not HTTP this is causing the error.
Here's the config for this particular site.
