I have a simple static sveltekit website configured behind traefik and
cloudflare.

When I go on test.example.com it works, when I click on a hyperlink
for /about it takes me to test.example.com/about and it works.

When I try manually going to test.example.com/about it returns a 404.

For another website on just example.com I don't encounter this issue.
I can directly go to example.com/about and it works.

If you edited your post to include your Traefik config it might be
easier for people here to help spot the issue.

But taking a guess, it sounds like maybe an issue with the
[rules](https://doc.traefik.io/traefik/routing/routers/#rule) you have
set up for the router to test website?

Or maybe do you use a [redirectregex](https://doc.traefik.io/traefik/m
iddlewares/http/redirectregex/) (maybe to redirect http requests or to
add in a leading www.), maybe the it doesn't handle paths correctly?

I have updated the post with my config. I use the same labels for
example.com where I don't encounter this problem.

Thanks for adding some config.

Nothing jumps out to me as looking wrong. Maybe try replacing the
$DOMAIN alias with the hardcoded domain name just as a sanity check
that it is carrying through correctly?

     --label traefik.http.routers.$TRAEFIK_ROUTER_NAME.rule=Host(`test
.example.com`)

Assuming you only have that host rule and no other "path" or
"pathprefix" or "redirect" middlewares, then (as far as I know) any
request for the test.example.com subdomain incoming to the http or
https entrypoint on traefik (regardless of path after the domain)
should be redirected to the service.

You likely already have but maybe take a look at the access logs for
the test website to see if it the request is getting as far as it
before the 404 is returned.

I've checked the labels and the Host in
[test.example.com](https://test.example.com)

I seem to be getting GET /test HTTP/2.0" 404 124 "-" "-" 9
"subdomainwebsite@docker for my test.example.com and
GET /test HTTP/2.0" 302 0 "-" "-" 6 "rootwebsite@docker for my
example.com website.
