(please excuse my bad english)
I’ve just setup my instance on a new dedicated server and it seems like Discourse is showing on every domain pointing to my server’s IP.
This is a problem because I think this IP was used by an other site back in time and now when I search “mysite.com” in Google, there are a lot of results from “oldsite.com” which is indeed pointing to my Discourse instance.
How can I redirect users which arrive on the server with oldsite.com domain name, or show an error page ? I know how to do this whith Apache vhosts but Docker and RoR server are new for me.
Thank you for your help.
