TLS passthrough not working

Traefik Traefik v2 (latest)
1

Hi,
I am using traefik 2.10 and currently I use ingress and ingress route setup on my traefik to route traffic to various backends and we are terminating SSL at traefik level. Now I am looking at ways to do TLS passthrough to my backend loadbalancer and route traffic from there.

My current Ingress set up is as follows. I deleted this so as to add a TCPRoute for passthrough.

kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: traefik-public
    meta.helm.sh/release-name: test
    meta.helm.sh/release-namespace: test-beta
    traefik.ingress.kubernetes.io/router.entrypoints: websecure
    traefik.ingress.kubernetes.io/router.tls: "true"
  labels:
    app.kubernetes.io/instance: test
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/name: test
    app.kubernetes.io/version: 1.0.1
    helm.sh/chart: test-0.1.179
  name: test
  namespace: test-beta
spec:
  ingressClassName: traefik-public
  rules:
  - host: '*.test.com'
    http:
      paths:
      - backend:
          service:
            name: my-test-service
            port:
              number: 8080
        path: /
        pathType: ImplementationSpecific
  tls:
  - hosts:
    - '*.test.com’```

I deleted
1. The above Ingress
2.  kubernetesCRD and kubernetesingress providers I have in my existing configuration 

Added the following to allow for TLS passthrough. All my traffic is HTTPS

```apiVersion: v1
items:
- apiVersion: traefik.io/v1alpha1
  kind: IngressRouteTCP
  metadata:
    annotations:
      ingress.kubernetes.io/ssl-passthrough: "true"
    name: test
    namespace: test-beta
  spec:
    entryPoints:
    - websecure
    - web
    routes:
    - match: HostSNIRegexp(`^\w+\.test\.com$`)
      priority: 1
      services:
      - name: test
        namespace: test-beta
        port: 8080
    tls:
      passthrough: true
kind: List```

Whenever I hit my website on browser I see the following logs
time="2024-03-29T16:50:41Z" level=debug msg="Serving default certificate for request: \"api-a1b2c3d4e5.test.com\""

time="2024-03-29T16:50:41Z" level=debug msg="http: TLS handshake error from IP:41614: remote error: tls: unknown certificate authority"

Where do I add certs in IngressRouteTCP config?

Use 3 backticks before and after config to format correctly.
