All .orb.local domains return ERR_CONNECTION_REFUSED error #2644

Describe the bug

I'm having an issue with OrbStack where *.orb.local domains are no longer resolving.

To Reproduce

1. Start any Dev Container project
2. In OpenStack, find the running project in Containers list
3. Click on the domain listed in Info tab
4. Observe the website NOT loading in the browsers

Expected behavior

Running the container app on https://{container-name}.orb.local should load the app in the browser; instead the request times out with ERR_CONNECTION_REFUSED error

However, running the container app on http://localhost:3000 works as expected.

Screenshots and additional context (optional)

Something has changed in my mac's configuration; whether it was OrbStack configuration, or another app Like Tailscale altered the network configuration, and now all .orb.local domains stopped working.

I deleted OrbStack.app, and all references I could find in ~/.orbstack, /Library/Application Support and ~/Library/Application Support. Then, reinstalled OrbStack; but made no difference.

Not sure whether any of these files should exist for the OrbStack and macOS versions I run, but based on other similar issues, here's some diagnostics:

cat /etc/resolver/orb.local 2>/dev/null || echo "FILE_NOT_FOUND"
FILE_NOT_FOUND

cat /etc/resolv.conf 2>/dev/null | head -30
