And my Discourse not work if I’m change subdomain.  
Example when install I’m enter this hostname: [1.example.com](http://1.example.com)  
So now I want to use Discourse with 2 hostnames: [1.example.com](http://1.example.com) and [2.example.com](http://2.example.com).  
It’s not work. Discourse work only with one hostname: [1.example.com](http://1.example.com).
