code LGTM, but please check CI.

looked like some tests were failing as Astro Dev environment was down for sometime yesterday, tests are working fine now

FWIW, we just updated to astro CLI 1.11.0 where this change landed and it breaks our development setup, which is:

1. Run astro dev start on a remote server (in our case a VM in Azure where we connect over ssh)
2. Setup port 8080 forwarding from that remote machine to the laptop where we run a browser to access the Airflow UI

But because of this change, the web server will only listen on the localhost/127.0.0.1 and the port forwarding will not work.

We are already aware of this issue and are working on a fix/workaround. We will try to land the fix in the next release. Thanks for reporting it @tehe
