Answer 1

For those heroku users using godaddy previously, I just finish porting the DNS over from godaddy to cloudflare. And the https is working fine now.

Godaddy DNS is incompatible with heroku. And this is due to:

Some DNS providers will only offer A records for root domains. Unfortunately, A records will not suffice for pointing your root domains to Heroku because they require a static IP. These records have serious availability implications when used in environments such as on-premise data-centers, cloud infrastructure services, and platforms like Heroku. Since Heroku uses dynamic IP addresses, it’s necessary to use a CNAME-like record (often referred to as ALIAS or ANAME records) so that you can point your root domain to another domain.

Setting up is fairly simple.

First, add the nameservers of the cloudflare into godaddy dns manager. These are some examples:

roxy.ns.cloudflare.com sam.ns.cloudflare.com

Next, you only need two more steps.

1. Add a CNAME NAME.com and link it to NAME.com.herokudns.com
2. That's it. This is assuming that you already have a CNAME www.NAME.com linked to www.NAME.com.herokudns.com

If you are using Rails, be sure to set config.force_ssl = true at config/environment/production.rb
