Multi-tenant Heroku app with SSL + GoDaddy SSL on custom domains

I have a multi-tenant Heroku app running Ruby on Rails with a wildcard SSL certificate on *.xyz.com which serves https://customer1-app.xyz.com securely & as expected. The problem is I can't add a GoDaddy SSL certificate to a custom domain (customer1.com) also at Godaddy pointing to one of the subdomains (customer1-app.xyz.com).

The approach I'm trying is fully described at here: https://help.heroku.com/8P5TVA4T/how-can-i-configure-multiple-ssl-certificates-for-a-single-app

Simply put:

  1. I created a shell application customer1-endpoint on Heroku
  2. I added the SSL-Endpoint addon & installed the certificated bought from GoDaddy on the shell application
  3. I copied the endpoint (DNS target - abc.ssl.herokudns.com) from the Heroku CLI to theCNAME record of GoDaddy
  4. I added the custom domain (customer1.com, www.customer1.com) to my main production (xyz.com) Heroku app

When I try to access https://www.customer1.com/ I receive a "No such app" message on Heroku. Any ideas what's going on wrong?

Solution

  • For anyone coming through Google, my issue was that I had my SSL-endpoint in a different region than my main app. This approach works, make sure that both apps are on the same region.
