问题
Any ideas why I might be getting the "No Such App" error when I go to my herokussl.com URL (after adding a cert and Heroku SSL endpoint)?
I followed the instructions here (https://devcenter.heroku.com/articles/ssl-endpoint), and got a herokussl.com URL.
I really don't think it's a DNS issue - as I haven't even gotten to that step.

It appears you can't access sites directly through the herokussl.com - which kinda makes sense, since they already provide wildcard ssl on herokuapp.com. I've just tried this with a production site I have which uses SSL and get the same "No Such App" if i access the herokussl.com domain directly.
If you CNAME your custom domain to the herokussl.com domain that were provided or from heroku certs and make sure you've added the custom domain to your application via heroku domains:add <customdomain> then it works fine.
