Heroku SSL added but visiting domain still says connection is not private

I contacted the heroku support, my problem was fixed.

1, set your CNAME correctly(I used the namecheap domains)

2, after that, check that the heroku DNS target is the same as the namecheap host value.

3, restart the ACM (ssl)

4, you need to wait for several minutes to check the website.

Heroku has a new ssl implementation: https://devcenter.heroku.com/articles/ssl

The asker appears to be using this new implementation. For this implementation, it's required to set the CNAME in your DNS Management as mycustomdomain.com.herokudns.com. You do not need to reference your certificate name, brachiosaurus-94028 in your case.

When you add the SSL addon to Heroku, it generates a new domain, and you should use it as your CNAME value, and it's not the original herokuapp.com anymore. The heroku certs command should give you the domain you should use, which ending is herokussl.com

In your case, you probably should set the value of your CNAME as brachiosaurus-94028.herokussl.com (you can test the endpoint on your browser to see if it works).

It should not take so much time for it to work also (when I do this it is always instantly)
