Hi,

I’m trying to make a two separate Discourse forums (including users, topics, categories, etc.). However, when I get a new instance and try to host it with the same domain, but a different subdomain, it takes my current Discourse instance and makes it inaccessible.

For example, if my current Discourse runs at [discourse.example.com](http://discourse.example.com), then I try to launch a second Discourse at [discourse2.example.com](http://discourse2.example.com), then the existing instance stops working and nothing is shown in the second URL. However, I can just rebuild the first Discourse at [discourse.example.com](http://discourse.example.com) and my first instance is restored.

During the setup, all the settings were the same as the first except for the Discourse Hostname. Can anyone explain why this happens and how I can make a fresh instance for [discourse2.example.com](http://discourse2.example.com)?
