为带有子域的heroku应用配置CNAME

Question

Currently i have an app on Heroku with a wildcard subdomain working like this:

client1.myapp.com, client2.myapp.com, ...

This is working fine. Then, i'd like that each client can access this apps using their own personal domains. So, testing this on my personal domain, i would like to configure test.mydomain.com like this:

CNAME test --- client1.myapp.com

But, this is not working yet. I keep getting the heroku error 'No such app, There's nothing here, yet.' .

Not sure what i am missing. Is it a problem related to my actual Laravel app? Heroku config? DNS?

Thanks in advance for any help.

Assuming your application will provide an hostname for each client (actually, it would probably be preferable to have a single hostname as in any case it looks like they will all point to the same Heroku app), then you have to complete all these tasks in order to make it work:

1. Add the subdomain client1.myapp.com as domain attached to the Heroku app
2. Configure the DNS record for client1.myapp.com
3. Ensure client1.myapp.com resolves ( dig client1.myapp.com )
4. Add the customer subdomain/domain to your Heroku app, otherwise Heroku will reject routing the requests for that domain
5. Configure the DNS record for the customer subdomain/domain to CNAME client1.myapp.com
6. Ensure the customer subdomain/domain resolves

According to your issue description, I assume you probably did not configure the customer subdomain/domain as domain to your Heroku app .
