Some sites missing theme when using socket activation

[sharmay]

Host - Fedora coreos 41
Engine - Podman rootless

I was testing #6573

~/.config/systemd/user/caddy.socket

[Socket]
BindIPv6Only = both
ListenStream=80
ListenStream=443
ListenDatagram=443

[Install]
WantedBy=sockets.target

Caddyfile (poartial)

{
	auto_https disable_certs
	admin off
	default_bind fd/3 {
		protocols h1
	}
	default_bind fd/4 {
		protocols h1 h2
	}
	default_bind fdgram/5 {
		protocols h3
	}
}

https://homepage.example.com {
	import my_subnet_only
	import my_tls
	reverse_proxy homepage:3000
}
https://git.example.com {
	import my_tls
	reverse_proxy forgejo:3000
}

When I visit homepage.example.com I a page without theme, No error in caddy log, no avc denied, no error in chrome. Here is screenshot.

if visit :3000 I get properly themed page

I am seeing similar issue with paperless-ngx, jellyfin.

Only site which works correctly is git.example.com based on Forgejo, and home assistant.

What am I missing or how to debug this issue?

Check your browser's network tab, look at which requests are failing to return the correct content. I'm certain this doesn't have anything to do with socket activation.

Enable the debug global option, show your Caddy logs, show example curl -v requests for the failing URLs.

curl -v is showing identical output.
I opened it in Firefox instead of chrome and page renders properly.
