Custom Hostnames with Heroku

I’m having some trouble connecting Custom Hostnames within Cloudflare to my Heroku Application.

Within Cloudflare:

  1. My custom fallback hostname (which is is setup. Cloudflare is confirming it’s active.

  2. I added a a custom hostname (called “”) and confirm it is active. Cloudflare is confirming it’s active

Within Heroku:

  1. I have a Cloudflare Cert set up and the DNS settings are pointing to the “colorful-eggplans-iv4i6i…” DNS Target

The Current Result

  1. I see a screen that says “There’s nothing here, yet.”.

Heroku Support Says:

I could confirm the configuration of the domain on Heroku. But we are not able to confirm if you are redirecting the domain to on Cloudflare's side.

I believe the issue of you not seeing the same output is that the redirection of the domain is not happening properly on Cloudflare's side. Have you reached Cloudflare for details regarding this?


Any suggestions on how to fix this? Thank you!
