Sablier not working when upgrading from caddy 2.7 to 2.8.4

[accforgithubtest]

I have had a working set-up, using caddy + docker-proxy + sablier for a while now, using version 2.7 and things have been mostly working fine.
The custom builds are from serfriz/caddy-custom-builds.

When I upgrade to the latest version 2.8.4, all the applications that do not have sablier enabled are working fine.
For applications that have sablier enabled, it looks like they are not getting started by sablier, I end up getting a blank page in the browser.

If I start the container manually, then I am able to access the application from browser.

I do not see any error logs in both caddy and sablier containers.

Below is the critical bits of the compose files -

Context

• Sablier version: 2.7 -> 2.8.4
• Provider: docker 27.4.0
• Reverse proxy: Caddy (with docker proxy and sablier enabled). 2.7 works fine. 2.8.4 has issues.
• Sablier running inside a container? Yes.

Expected behavior
Expect sablier to start the containers and redirect to the correct page.

With the below, version 2.7works fine, while the latest (2.8.4) doesnt work.
