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?
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.
