Adding certificate for heroku app

Question

After I have followed the instructions on heroku to add a certificate from DNSimple, I still have this error when I try to access the website:

www.web.com uses an invalid security certificate.

The certificate is not trusted because no issuer chain was provided. The certificate is only valid for the following names: *.herokuapp.com , herokuapp.com

(Error code: sec_error_unknown_issuer)

So, what could be the problem?

Answer 1

Your hostname points to the Heroku generic app endpoint.

➜  ~  dig www.dcaclab.com +short
web.herokuapp.com.
us-east-1-a.route.herokuapp.com.
54.243.166.168

The CNAME should point to the Heroku SSL endpoint.
