traefik ingress: Allow all paths

Traefik Traefik v2
1

I've created this IngressRoute:

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: traefik-graylog
spec:
  entryPoints:
  - web
  routes:
  - kind: Rule
    match: Host(`graylog.localhost`)
    services:
    - name: graylog-web
      port: 9000

I'm able to reach it:

$ curl -I graylog.localhost
HTTP/1.1 200 OK

Nevertheless, this web is trying to get access to _/api, and it's getting me:

We are experiencing problems connecting to the Graylog server running on http://graylog.localhost/api/. Please verify that the server is healthy and working correctly.

As you can see, it's telling it's not able to reach _/api, where _ is graylog.localhost.

I guess I need to modify my IngressRoute but I don't quite figure out what I need to change.

I've tried to cahnge rule:

routes:
    kind: Rule
    match: Host(`graylog.localhost`) && PathPrefix(`/*`)

However, then I'm not able to reach root:

curl graylog.localhost
404 page not found

Any ideas?
