I just recently added the SSL Endpoint add-on to my "example" app, and updated my SSL Cert and Private Key from DNSimple to Heroku (according to this article: http://ryan.mcgeary.org/2011/09/16/how-to-add-a-dnsimple-ssl-certificate-to-heroku/ ) thanks to this command:
$ heroku certs:add STAR_example_com-bundle.pem STAR_example_com-private.key --app example
Adding SSL endpoint to example... done
example now served by oita-4417.herokussl.com
Certificate details:
subject: /OU=Domain Control Validated/OU=EssentialSSL Wildcard/CN=*.example.com
start date: 2012-07-28 02:00:00 CEST
expire date: 2013-07-29 01:59:59 CEST
common name(s): *.example.com, example.com
issuer: /OU=Domain Control Validated/OU=EssentialSSL Wildcard/CN=*.example.com
SSL certificate is verified by a root authority.
But now, when I try to access to my app with https://example.com (and sub-domains such as https://foo.example.com), I have a warning (inside a big red page, using Chrome)...
How could I fix this? Maybe I have to wait some hours? Thanks!
