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.
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.
