将子域和root / www指向不同的Heroku应用

Question

I've been trying to set up the DNS for a couple of apps using the same domain.

I want www.playfade.com and playfade.com to redirect to playfade.herokuapp.com, so set up a CNAME and ALIAS respectively to point to the Heroku app. This works fine.

I also want beta.playfade.com to point at soundedout.herokuapp.com. To do this, I set up a CNAME for beta.playfade.com to soundedout.herokuapp.com. This, however, doesn't work. When I access beta.playfade.com, I'm redirected to www.playfade.com.

I used MXToolbox to check beta.playfade.com and was given a few errors:

  Bad Glue Detected Parent server gave glue for beta.playfade.com to be soundedout.herokuapp.com but we resolve that hostname to 176.34.187.173 At least one name server failed to respond in a timely manner Failure detail: 176.34.187.173 Local NS list does not match Parent NS list 50.31.242.53 was reported by the parent, but not locally 198.241.11.53 was reported by the parent, but not locally 198.241.10.53 was reported by the parent, but not locally 50.31.243.53 was reported by the parent, but not locally 176.34.187.173 was reported locally, but not by the parent Serial numbers do not match 

I've set up the domains correctly in the heroku dashboard as well.

Any help would be appreciated.

There is no CNAME configured for the hostname beta.playfade.com . Make sure to properly configure it, and make sure you have no redirect configuration inside the app (or if you have it, tweak it accordingly).
