Comment 22 for bug 2028170

FYI I found that I had an old entry in /etc/hosts for this target domain to the localhost.
In effect it was fetching the (VALID) wildcard cert from my dev server (localhost) instead of reaching out to live server.
The wildcard cert on localhost is valid, though, (t1.skywaytheatre.com), so the error still indicates a bug, however this may be considered a special use case i.e.
CURL error when destination is localhost and cert is wildcard

Thanks
