How to remove default hostname?

[greg]

Hi,

Unfortunately you can’t disable the default domain. You would have to find some way to prevent that working yourself, perhaps with a redirect.

Take a look at this thread for some additional thoughts:

Disable the default domain

I just set up a custom domain for my app, how do I disable now the default [app].fly.dev domain, so the app is available only on the custom domain? Is that something I can do only on the app level (e.g. a force redirect), or there is a setting somewhere?
