I'm trying to use a domain name I have on Namecheap with Heroku. Heroku's documentation advised a CNAME Alias. In the past, I've gotten other domains on the same service (Namecheap) to work with Heroku, but I can't get this domain to work. I followed Heroku's instructions and imitated the way the other domains are set up.

Using Namecheap's web tool, I changed "All Host Records". In that section, I have:

@ http://www.example.com URL Redirect
www example.herokuapp.com CNAME (Alias)

set up at the top of the page. In Heroku's app settings, I can see that www.example.com is a domain of example.herokuapp.com, which I configured with the command line. When I go to www.example.com, however, I get

The server at page "www.www.example.com/?from=@" is not responding".

Any ideas how to fix it? I already tried manually changing the DNS to Google's servers, as well as using just about every variation of my domain. The additional www and /?from=@ seems to be a clue, but I'm not sure what's causing it.

To be clear, my objective is running my Heroku app through www.example.com

  • CNAME is not a redirect. It is an alias. Any CNAME equates a sub-domain to a domain name though trickier associations can be made. When you use a CNAME you would point it to a domain name or sub-domain that resolves through ordinary means. I am confused by your question. Can you tells us more about the tools that you are using and the mechanics of what you are trying to do??

  • A bit clearer. Typically, a CNAME is used to alias www to a domain name. It would be www.example.com -> example.com. What is important is to use the full sub-domain name and domain name (www.example.com) and not just the sub-domain name (www) assuming I am recalling correctly. So I would suggest trying to change the www in your second line in your example to a full sub-domain name/domain name specification. If that is not enough, try associating it to your domain name instead of your hosts domain name.

  • What do you mean by associating it to my domain name? Commented Mar 9, 2015 at 17:23
  • I was making an assumption that you had a domain name which may not be the case for what you are doing. Still somewhat confused as to whether you have a domain name that you registered or not. Sorry.

For anyone who has this issue come up, changing the DNS to v1 using Namecheap's online interface and then setting the "@" row to blank fixed the issue.
