user123424234 asked:
I’m trying to create a cname that points from my custom domain (s.mydomain.com) to a multilevel subdomain hosted on heroku (me.myapp.herokuapp.com).
I’ve created the Cname s.mydomain.com with the value me.myapp.herokuapp.com. When I go to s.mydomain.com it does not route to me.myapp.herokuapp.com, instead I get:
method=GET path=/ host=s.mydomain.com dyno=web.1 queue=0 wait=0ms connect=4ms service=18ms status=404
It’s possible I’m not fully understanding how this Cname should be setup. My desired outcome is for s.mydomain.com to act as if it were at me.myapp.herokuapp.com.
My answer:
Follow along the documentation carefully. There are exactly two things you need to do:
-
Tell Heroku about your subdomain.
heroku domains:add s.mydomain.com -
Set the CNAME record in your DNS.
s IN CNAME mature-infant-1234.herokuapp.com.
